Broken Windows Phone Marketplace
Recently the Windows Phone Developer Team posted an article about how App Insights work and specifically how Free, Top, and New apps work. It’s all accurate, a good read, and (to an extent) will help you improve your app’s ranking in the Marketplace list.
However there continues to exist a few underlying problems with the Marketplace, specifically for independent app and game developers, that has yet to be fixed. This isn’t the first time someone brought this and I blogged about it over a year ago when the Marketplace had about 10,000 apps. There’s even a user voice item to show trial apps that you can vote on.
While I hate being a “this is broken” it seems that if you don’t call people out on things, they just let them linger and hope someone else fixes them. This is somewhat like the broken windows theory that breaking a few windows in a building and not repairing them leads to more disrepair which then spreads to other areas. The idea is to fix a broken window when you see it and keep things fresh and working. To me, most of these broken windows have been in the Marketplace since day one and in some cases, new ones have appeared since the launch of the web-based Marketplace.
Apps vs. Games
This is probably the biggest issue, next to the XBox LIVE one below. When I visit the Marketplace on the web I see this listed for Apps:
And here’s the home page listing for games:
That’s all well and dandy but what if I click on the “Top” filter under Apps. This is what I see:
No, that isn’t a Photoshop with a mislabelled title. It really is the “Top” listing of apps.
Even though apps and games appear separated, they still get lumped together when you view the “Top” listing (because in the grand scheme of things, Angry Birds is way more popular than YouTube or Facebook).
To me this is wrong. Games have their own grouping. In fact they even have an entire page to themselves:
So why are they being lumped into the Top rankings for Apps?
It gets even worse when you click on Apps from the home page to view all of the app and their sub-categories then click on the Top listing for Apps:
Yes, that’s the Top “Apps” in the all category. Is there a single app in that list? No, you have to scroll down (at least in my marketplace, every marketplace ranking is different) to the 12th icon before it’s an actual app (which is then followed by another 8 games before getting to the 2nd top app).
So basically “Top” apps and games is broken. Plain and simple. If you build a kick-ass app that rises to the top don’t hold your breath to hope it will appear in the “all top” listings because you need to climb above all the XBox live games first. With a separation on the site of Apps vs. Games, this is unacceptable.
Suggestion: If you go the distance to separate Apps vs. Games (like you have done) then go the distance and keep them separated. Don’t show me XBox LIVE titles when I’m asking for the Top Apps.
XBox LIVE
This brings us to the second most annoying “feature”. The Games section of the Marketplace offers a new “XBox LIVE” tab. This will filter out indie games and only show you ones that have been created by Microsoft and other studios for XBox LIVE (i.e. they get to participate in the official achievements and points system).
That’s great if you’re looking for an XBox LIVE title. Just click on it and boom, Bob’s yer uncle.
However why do I see this when I click on the Top games:
Yes kids, just like how these titles bubble up to the “top” of the app listing, they also bubble up to the top of the game listing.
Unfair? You betcha. XBL have a tab of their very own and right now there’s only a few dozen titles. So why in the name of all that is holy are you injecting XBox LIVE titles in to the Free, Top, and New tabs?
Okay, I get it. How would you sort out XBL free, top, and new titles from each other? Fair question but since you have a tab of your very own for XBox LIVE why not go the extra distance and have a Free, Top and New tab or filter for just XBL titles.
In other words, an indie game developer has a snowballs chance in Hell of getting into the Top listing for games (or apps for that matter) when trying to face off against the juggernaut of Microsoft Game Studio titles. Of the *Top* 20 games in all categories, only 1 is a non-XBL title.
Suggestion: Please keep XBL titles out of the filtering from the rest of the games. If you give them a sandbox to play in like you did, then let them play there and stop peeing in our sandbox.
Trial
The third issue here is that of Trial visibility. Do you know how to see if an app or game has a trial version? Click on the details for each individual title and you’ll see it on the page under the price:
There it is. On Each. Individual. Page.
So trying to browse to see what’s a trial vs. not isn’t possible. The system knows they’re trials but they won’t tell you until you look at each individual one.
Suggestion: Include a Trial tab or filter or search box or something. Let us see what’s available as a Trial without having to drill into each title.
To me, the Marketplace is broken on a few levels and it’s difficult (if not almost impossible) for people to get visibility above the AAA titles. Here’s hopes that Microsoft might be listening again and perhaps look into it. If you don’t agree things are broken then just consider me the crazy white dude on the corner yelling about doom and gloom and move on. If you do agree, voice your opinion as comments, tweet this, blog about it, whatever. Lets see if we can instigate change.
Thanks!

Displaying Large Text Files in Windows Phone Apps
Have you ever needed to provide instructions or help for your Windows Phone app and found yourself creating gobs of XAML and writing it in the Visual Studio designer into a TextBlock control? Not very efficient is it? Here’s a technique you can use that might make things easier.
Ingredients
- 1 Text File (preferable something appropriate to your app)
- 1 Phone Application Page
- 30 Lines of Code
Preparation
Create a new Phone Application Page (or use an existing one). Add a ScrollViewer to it like so:
<!--ContentPanel - place additional content here--><Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ScrollViewer x:Name="ScrollingTexFromHell"/>
</Grid>
You’ll need a text file to display so create one in your project. By default it’s type is set as Content so that’s what we want. Just make sure the file is copied to the project (you can choose to copy always or copy if newer, doesn’t matter). I use Bacon Ipsum to get me some sample text because well, it’s bacon baby.
In the code behind add a method like this:
private static StackPanel TextToXaml(string filename) { var panel = new StackPanel(); var resourceStream = Application.GetResourceStream(new Uri(filename, UriKind.RelativeOrAbsolute)); if (resourceStream != null) { using (var reader = new StreamReader(resourceStream.Stream)) { string line; do { line = reader.ReadLine(); if (string.IsNullOrEmpty(line)) { panel.Children.Add(new Rectangle { Height = 20.0 }); } else { var textBlock = new TextBlock { TextWrapping = TextWrapping.Wrap, Text = line, Style = (Style)Application.Current.Resources["PhoneTextNormalStyle"], FontSize = 22, }; panel.Children.Add(textBlock); } } while (line != null); } } return panel; }
Finally add a Loaded Event to your page to execute this when the page loads and assign the value of the method above to your ScrollViewer.
// Constructor public MainPage() { InitializeComponent(); Loaded += OnPageLoaded; } private void OnPageLoaded(object sender, RoutedEventArgs e) { ScrollingTexFromHell.Content = TextToXaml("mytextfile.txt"); }
The Result
The code is really simple. It just reads in the text file as a stream and reads each line in the text file. A StackPanel is created in our method and whenever the reader hits a blank line it inserts a small rectangle, otherwise it creates a TextBlock control with the content set to the line. You can adjust the height of the space between paragraphs and the font style and size but I picked something that I think looks pretty good when reading long text.
The paragraphs are stacked up in the StackPanel control which is then set as the content to the ScrollViewer we inserted. The user can just scroll through the entire text as they need to.
Enhancements? Of course. You could
- Put this into a Phone Class Library and use it as you see fit (you could even create a NuGet package!)
- Add parameters to the TextToXaml method like font size and spacing
- Do extra things with the reader while processing the text. For example you could recognize a new line and make each new line bold or larger so the first line in each paragraph would be a heading.
Have fun with it. It’s simple and I find it’s better than entering the text into the XAML page directly.

Official and unofficial apps in the iOS, WP7, and Android marketplaces
The last few months have seen people complaining about the lack of "official" apps in the Windows Phone marketplace. In fact a couple of months ago I wrote about this very thing here and if we really needed these official apps or could get by with third-party solutions.
Recently a list of "Top 100 Mobile Apps" crossed my desk and it was curious. 40 iPhone apps, 40 Android apps, 10 WP7 apps, and 10 BlackBerry apps. Really? 10 for WP7? So I wondered if the media was just playing this up and maybe continuing to do what I think most vendors are doing which is treating Windows Phone as the red-headed step-child you keep in the basement while all along there's nothing wrong with them.
I put together the list and went digging to see how many of the top 40 iOS and Android apps were also on the Windows Phone platform (sorry BlackBerry, you should just shut your doors right now). Here's the results. Note, these are all *free* apps. There might be other pay apps that have official representation across all mobile devices, I just chose to hunt these ones down because I'm cheap.
In the top 40, I easily plucked out 20 that had official apps on all three platforms. These were: Amazon Mobile, ESPN Score Centre, Evernote, Facebook, Foursquare, Google Search, IMDB, Kindle, Shazam, Skype (yes, I know, in beta on WP7), SlackerRadio, The Weather Channel, TripIt, Twitter, Yelp, Flixster, Netflix, TuneIn Radio, Dictionary.com, Angry Birds, and Groupon.
Hey, that's pretty good IMHO. 20 or so apps, all free, and all fully functional and supported (and in some cases, even better looking on the Windows Phone platform than the other platforms).
A dozen or so more apps had official apps on some platforms but not all, so yes, there are gaps here. Here's a rundown of the hangers-on:
Adobe Photoshop Express
This looks great on the iOS platform and there's even an official version on droid. Hope Adobe brings this to WP7. There are other photo editing programs though if you go looking (maybe we can get Paint.NET to be ported to the phone?)
BBC News
A few apps offer news feeds but nothing official on the Windows Phone. The feeds are good but without video this app needs some WP7 love.
Dropbox
Again Windows Phone looses out here with no official app. There are a few third party ones that will help you along and offer most of the functionality that you need but no integration that an official app might bring.
Epicurious
Droid seems to be the trailer here as there are apps for it but nothing official (from what I can tell). Both iOS and WP7 have them.
Flipboard
It's sad with Flipboard as it's such a great newsreader. The only offiical app is for iOS but frankly the iPhone version looks horrible so without a tablet the experience here isn't that hot. Maybe with WP8. Currently there's nothing even remotely similar to this on the other platforms.
Google+
Is anyone still using this? No official app for WP7 but some clones. Apparently there's no API so people are just screen scraping. Ugh.
Mint.com
This app has all kinds of buzz and a lot of votes on the application requests site. Official apps for iOS and droid. No WP7 love (yet).
TED
Quite a few TED apps on WP7 but nothing official. I think the third party ones suffice and some are pretty nice looking, taking advantage of the Metro interface and making for a good show.
WebMD
There's a third party app on WP7 here but nothing official. It seems to contain all the same information and functionality the official apps do so not sure if an official one is needed but its here for inclusion.
The other apps in the top 40 were either very specific to the platform (for example all three of them have a "Find my Phone" app). There are others that are missing out on the WP7 platform like ooVoo, Words With Friends, and some of the Google apps (Google Voice for example). Since you can integrate your GMail account right into the Windows Phone (via linked inboxes) I'm not sure if there's a need for an official GMail app here.
Looking at the numbers Windows Phone still gets the worst of the deal here with half a dozen highly popular "offical" apps that exist on the other mobile platforms and in some cases, nothing even remotely similar to the official app to compare. This doesn't include things like Instagram, PInterest, and others (don't get me started on those).
Still, with over 20+ highly popular free apps all represented on all three mobile platforms I don't think it's a bad place to be in. The Windows Phone platform could get a little more love from the vendors missing here, or at least open up your APIs so the third party crowd can step in and take up the slack.
P.S. these are just my observations and I might have got a few items wrong. Feel free to chime in with missing or incorrect information. I am after all human. Well, most of me is.

PrairieDevCon 2012 Sessions
As a follow-up to yesterdays note about my Windows Phone Developer Workshop (there's still room for more peeps!) here's a list of regular sessions I'm presenting at PrairieDevCon 2012.
SharePoint Client Object Model: Accessing SharePoint Externally Using JavaScript
In SharePoint 2010 there are a number of object models that can be used by developers to access the server. The Client Object Model (Client OM) is a unified model which uses the same or similar programming concepts as the Server Object Model (Server OM). The Client OM can be accessed via web services, via a client (JavaScript) API, and via REST. Everything from enumerating sites and lists, displaying list items, adding and creating content, and getting user information can be done all from the Client Object Model. In this session we'll explore the Client Object Model and create examples accessing SharePoint data using JavaScript and jQuery.
Application Design for Windows Phone
In the past year, we’ve worked with hundreds of developers and designers interpreting the "Metro" design system for their own purposes. We’ve seen great interpretations, and others that aren’t so great. In this session, we’ll share with you the foundations of great Metro application design for Windows Phone, and how to use them to build outstanding applications that will stand out and get noticed… for good reasons. We will also be providing some general best practices for building great mobile experiences.
The Marketplace – What Makes a Successful App on Windows Phone?
If you are a developer and have even thought about developing Windows Phone lately, you likely already know that every app and game that is installed on consumer Windows Phone 7.5 devices comes from the Marketplace. This is new to the traditional Windows Phone ecosystem prior to version 7, and while in some cases this does introduce a change for developers and users, there is a lot of reasons why this change is a great one. In this session, we go through both the consumer and developer/publisher experience on the Marketplace and strategies for distributing your app and game both publicly and privately. We will also provide an overview of our Marketplace presence around the world and what new countries have been introduced with the release of the new 7.5 (formerly codenamed “Mango”) update. Finally, we will provide you with strategies on how to increase the popularity of your applications and games and (if you are charging a price for your masterpiece) how to make more money.

Get Juiced with me and 10,000 friends at Prairie Dev Con West
I”m happy to say that Prairie Dev Con West 2012 is almost upon us. In just over a week geeks from the five corners of the planet will get together and talk about D’Arcy Lussier’s hair and hope that the Mad Mexican doesn’t crash their session.
For me there’s a few sessions I’m presenting including a day long workshop on Windows Phone Development. If you’re looking to learn hands-on development with a Jedi Master then you’ll need to find a different conference. If however you want to try your hand at learning with me and watch me stumble through trying to run Windows on a MacBook Pro, then bring it. Here’s a rundown of what we’ll be covering with the Windows Phone Developer Workshop.Start your engines and we’ll go from 0-11 in 60 minutes with building more Hello World apps you’ve ever seen. They’ll be a Hello app, a World app, and even a Hello World app. Everything you need to know to get started with Windows Phone development. After a series of Hello World apps you’ll be ready to build anything (well, anything with the words Hello and World in them)
- Everyone talks about the Model-View-ViewModel (or as we experts say MVVM) pattern when it comes to data binding on the Windows Phone. We’ll explore every concievable angle to using the MVVM pattern, tools that make it less painful to implement the pattern, and different ways we can spell MVVM (like MVMV, MVCM, and the ever popular MCMXXVII)
- For me I’m all about the bling and love to criticize apps that make my eyes bleed. Help me make my eyes bleed less by learning the Metro design language. We’ll just randomly pick ones in the marketplace and rip them a new one. If you like watching Gordon Ramsay yell down at people that cook like donkeys then you’ll fit right into this part of day. I guarantee you’ll know the Metro ways after this or I’ll beat your with your own skull.
- Mango introduces about 800,000 new API features and we’ll look at every one of them in detail. There are some cool tools that will help you debug and work with apps in the emulator and we’ll go over the new and old stuff in Mango. This part of the session may extend the day so bring a sleeping bag and some Red Bull to keep you going through the night.
- Expression Blend is the most complex piece of software ever known to man. We’ll try to figure it out. Barring that, we’ll just sit around and sing Kumbaya and make jokes about people from Edmonton.
I’m also presenting a session on using the JavaScript Client Object Model with SharePoint 2010. We’ll build some funky stuff and learn how to iterate lists, sites, and build alternate UIs for SharePoint without writing a single line of C# code. There are also two additional sessions on Windows Phone that I’m planning on doing which is a deep dive into marketing and design. Oh yeah, there are other people doing sessions at the conference too.
The 10,000 friends? Okay, so I think the attendance for Prairie Dev Con West is only a few hundred, but I like to use my imagination and pretend I can see ten times more people than there really are. Same effect when I drink.
In any case, if you haven’t registered already please consider it. D’Arcy puts on a damn good show and the quality being presented here (sans me) is top notch and there’s a huge diversity of sessions to take in.
Also remember the pre-con day-long workshops are there. If all you want to take in is a workshop, that’s cool too and you’ll get a full day earful of Agile, Windows Phone Development, and TFS Build sessions. Still an absolute cheapskate like me? Then there’s a day long Windows Azure Boot Camp you can come out to that absolutely free (as in beer, but space is limited) and even includes breakfast and lunch (sorry, the Microsoft IT Virtualization Boot Camp is sold out).
Come on down and get smart(ish).

InstaCam MetroMakeover - Spacing, Margins, and Polish for your Windows Phone App
In the spirit of a recent article that Jeff Wilcox posted on his blog about the MetroRadio app, I thought I would do something similar for the InstaCam app.
InstaCam is a 3rd party app written by Dmitry Manayev to bring Instagram functionality to the Windows Phone platform. I contacted Dmitry about this post to get his permission. Here are a few tweaks that you can keep an eye out for in your own apps.
First up is the Popular Page. This has small square images of the most popular pictures currently posted on Instagram. The page is built on the Panorama control so the title is the default. It’s the pictures that are off a bit here. If they were indented 14 (or maybe 15) pixels then the edge of the pictures would line up with the pano title. Part of Metro is about lining things up and keeping it clean. You should see an invisible line down the left side of your pages that align things up. I saw the same margin issue on the search results page.
Next up is the search results page. I found the spacing to be a little tight so after measuring it I found that the spacing was in line with the minimum recommended target size from Microsoft, 7mm (check the guidelines here for target sizes). In the recommendations they suggest a target size of 9mm rather than the minimum of 7mm. The idea with Metro is to open up the design and make liberal use of white space. Don’t crowd things together if you can avoid it. There's plenty of space so hitting the target of 9mm (with perhaps a larger font) might open up the page a little more.
On the feed page there are a few little tweaks I would look at. First is the title for the app. The unwritten rule is that a page title should be in all CAPS. Hey, it’s a style. Check out (most) of the core apps and you’ll see the style applied there. Next is spacing. Jeff Wilcox mentioned there’s no hard and fast rule with vertical spacing (I really wish there was so we could all follow it, hint, hint) but he does say he tends to use 4, 6, 12, or 24 pixels. The default vertical on some of the initially generated XAML you get from Microsoft pegs some vertical space at 17 pixels so the message here can be confusing. For the title spacing I thought a 14px top margin would work here (but 12 would be fine too).
The thing about spacing is be consistent! I don’t think it matters if it’s 12, 17, or 24 but keep it the same on every page. That should be your mantra. Consistency. With vertical spacing (and especially page titles) watch out for the top margin where the system indicators are. If you leave them turned on, you lose 22 pixels. If you turn them off you get that back but remember to turn them on or off across your entire app (or compensate for pages where you have it turned on). For example Panorama pages have the system tray turned off by default so if your app goes from a Pano to a single page (or a pivot) then you might notice a slight “jump” with the title as it moves from a page without the system tray to one with.
Down in the details for a single picture it shows the user who took it, some information about them, and the likes and comments for that photo.
The name and when the picture was taken is a little crowded here and butts up against the profile picture. The suggestion here is to apply a 12 pixel margin to the left of the name (or the right of the picture) to open things up. In addition I would personally put the like and comment counts inside of the symbols (using white to offset the colour). That’s just a personal preference but it might make it a little tighter and gives you more space to be able to use larger symbols. There is a gotcha here of course with numbers inside of symbols. Some images will have 0 comments, other will have 10,000. I have seen a situation where the font scaled based on the width of the number so that might be an option. For sure when testing something like this you should consider ranges like this and try out the extremes. You might not be able to catch every scenario but don't just design for say 4 digits when the possibility of 8 exists for example.
When you view a single image I noticed a few things that a slight adjustment would fix. Again, a lot of these changes here are just minor tweaks to the UI, nothing major. I think this is the case for a lot of applications out there. A couple of hours going over things and moving a few items around goes a long way.
Here again the margin issue rears it’s ugly head. The margin for the Like button is fine (and bleeding the picture itself to the edge of the phone is a nice touch, lets you see more of the image). It’s the tags and detail labels. The colour doesn’t work against a dark background. Whenever you’re looking to highlight something consider using the PhoneAccentBrush colour (but use it sparingly). Dmitry did mention in the latest update that he fixed the colour to the blue phone accent colour. I took these sceenshots from the marketplace so maybe that hasn't been updated. On my phone the text does look better than here but again, watch out for themes when deciding on using accent colours, especially with fixed colour or image backgrounds.
As for the buttons, they’re a little off so as your eye moves horizontally across you see text jump up or down. It’s only a few pixels but a design technique mentioned by Arturo Toledo, a Senior User Experience Designer at Microsoft. On his UX blog he recently talked about the design process for Metro apps. In it he talks about Redlines, marked up screenshots of your app with lines drawn across and up to show alignment and spacing. This is something everyone should incorporate into their release process. Yes, my lines are magenta but that was just for clarity. Red, yellow, magenta, whatever works for you.
For the buttons themselves I would consider doing something with the extra space. Split the buttons (either using a Grid or a StackPanel with the Orientation set to Horizonal) so they’re evenly distributed (Width = 0.5* in the case of a grid). Then regardless of how much the content takes up, they’re consistent and not as jarring to the eyes. Again here I might consider putting the counts inside the symbols (to be consistent with the other views if you did that) but leave the words “Likes” and “Comments” so people know what it refers to. Here the words work because you’ve got the entire width of the phone to display them (vs. the previous image where there’s only room for the symbol).
Finally the user profile page. I would suggest a few small changes here just like the other pages.
For this page:
- Align the profile picture with the page title
- Align the counts and count labels (photos, following, etc.) on the left. This tends to be the norm rather than centered text which sometimes looks like its floating without an anchor. Again refer to the core apps for some guidance here, for example take a look at a persons profile page (your own or someone else). They’re a good model to follow.
- The colours here are awkward again and hard to read. If you use the PhoneAccentBrush colour then pay attention to how the light and dark themes work against your backgrounds. Sometimes when using background images you need to adjust the Opacity dynamically. When testing, just go through all of the Theme colours in both light and dark mode. It takes an hour or so with a few screens and all of the combos but you’ll cover all the bases.
That’s it. Hopefully that helps you in your own application development and gives you a few little things to look out for. They’re all minor tweaks but things that you can add to a final checklist of things to go over before you submit your app to the marketplace. Thanks for Dmitry for letting me write this post and perhaps he’ll put some of these suggesting in a future release.

Does the world really need "official" apps?
The "buzz" exploded a few days ago with this site. "Official" application requests for Windows Phone 7, vendors and services that don't have a presence (an official one anyway) on the Microsoft phone platform. I have to ask though, do we really need an "official" app?
Okay, let's take a few steps back before we go forward. What exactly is an "official" app. I would say it's a) an app written by the service owner (Instagram, Pinterest, Twitter, etc.) or maybe b) an app officially endorsed by the service owner. In any case it's considered sanctioned, blessed, whatever. Foursquare, Flickr, Groupon, Twitter, YouTube, etc. all have apps like this. In the case of apps like YouTube and Twitter you'll see the application publisher is Microsoft. These guys might have deferred the creation of the apps to Microsoft or the publishing or both.
People see these apps as *the* app they should get if they want to use that service on their phone. Apps turn into verbs and users are told to use Evernote to use their service on their phone. With the moniker of being an official app I suppose it carries a bit of levity as far as stability and reliability.
Or does it?
In the case of longevity it might be the case. As long as ESPN is on the air, they'll have an ESPN ScoreCenter app. Or will they? Budgets come and go so if I was a manager and looked at "trimming the fat" I might consider lopping off the mobile developers and abandoning that early. After all, how much revenue does a free app on a phone get you? I do think once the genie is out of the bottle that organizations will at least try to keep that division running and we haven't seen too many apps fall by the wayside. So yeah, it's probably a safe bet that "official" apps will stay around as long as the service is there.
On the reliability side it's a different story. What's the number #1 request on the user voice site right now? Facebook. Wait, that has an "official" app doesn't it? It was built by Clarity Consulting but looking at the comments on the uservoice site and on the marketplace you see things like "They need to fix this", "Add some new features", and "Need a lot of work!!". The Twitter app, IMHO, is another fine example of an "official" app generally gone wrong. No live tiles, it's been out for 16 months and it's only on version 1.3 and last time I used it I couldn't even do a "reply all" on a tweet. Frustrating.
Official apps may be no better than 3rd party ones out there so don't be fooled by the "official" title. Indie apps are built by developers with a passion, official apps might in some cases be considered an IT expense.
The first thing you have to look at, does the vendor or service have an app? On any platform. If they don't then the next question (besides should they) might be, is there a way to get one on there? Are there any data sources available. Obviously if they have a web presence then they have data but it may not be publicly consumable. If they do have an app, is it good enough. What are the reviews like? Is it meeting the needs of the many and providing a way to access their services to do everything. Is that the purpose of the app? Sometimes apps are supplements to the on-site services they have available and not a substitute. Aside from services, does the app work correctly, doesn't crash, is quick to respond, is updated frequently to align to new features the service offers, etc.
If they do have an API is it a) publicly consumable and b) is it full featured? One stumbling block I hit with producing an Instagram app for Windows Phone was that they didn't provide a way for users to register new accounts or upload photographs, a cornerstone to the service itself. This can be frustrating so before you embark on perhaps building something check to see if you can do it.
So what's the value-add for you building an application, either as the only application on that platform or a supplement to a broken or limited-functional "official" app? Are you making it better or filling in the gaps the official app is missing? What happens when the official app maybe catches up and delivers that functionality. Now you're playing a game with the official team and you might not win that battle. Something interesting with something like Foursquare is that the reviews are not too horrible (some good, some bad) but looking at the reviews and functionality of something like 4th & Mayor is that the official app came out long after Jeff Wilcox's version. Was it too little and too late? Jeff constantly updates the app not only for stabilization but new features. The reviews, UX, and stability of this "unofficial" app outweighs the popularity of the "official" one, although I think this an exception to the rule. Again, this is a good example of a labor of love vs. an IT project.
I think it's great we have the official apps on the Windows Phone but I think it's even better that we have public APIs, a nice development platform, and a passionate community that wants to do better. If all we do is accept the official apps then we're not pushing the envelope. Sometimes that's just not good enough and we as a community deserve better. Support it by showing your voice on sites like the Marketplace Request site, by blogging about it, and by pushing services to provide the ability for developers to step in and help out.
As for vendors and service owners, please do us a favor by exposing your APIs and letting developers do what they do best, develop. Focus on your service if you want and put it out there for others to pick up the ball and run with it. Keep on top of what's out there, help us by helping you, and you might be surprised in what we might be able to accomplish. It's like I tell game studios, focus on building your game. The development community will stand up and provide the supplemental tools that will build the community for you, you just have to give us the tools to do what we're passionate about.
