Been using this the past couple days to track me spending.. Working quite nicely.
I have a couple suggestions if you don't mind.
1)While adding a value to a record I think there should be some sort of "OK" button. The back button does exactly this, but it wasn't very intuitive for me. (I originally thought the back button would cancel what I have done.
2)Add a value to the accounts to show the current fund in that account. So If I have 100 in my bank account, I can add that to the account. Any record I add will either add/minus to that.

Any ways liking the app... I really need to cut down on my spending
