A first party Mint app is much in demand, but has also been long in coming. Winsource now reports that that developer Greg Wenograd has been working on a 3rd party app for Mint.com, the popular online money management service.
Greg has previously also created a 3rd party Pandora app for Windows Phone called Radio Controlled.
The Mint app is called Money Thyme and is in beta testing and supports charts, balances, budgets, alerts and more.
If that sounds like your kind of thing, you can sing up to be a beta tester for the app here.
