I personally use Quicken 2007 to track my finances. I don't use for each and every thing like how much cash I use but use it for where I can sync my accounts online so I can have history. Quicken is okay (not as bad as Money) and I don't have that many complaints but in my mind, I always thought if there's a free online tracker. You know Quicken/Money is not free and it's not accessible everywhere if I don't have my home laptop.
I just heard about Buxfer (non-ASP.Net application) and looks good as an alternative to Quicken or Money to me. Security is my first concern so I'll post again with my overall experience later.
Have you used?
