Must now sometimes give my two cents. When I read, you can not enter new categories to the other week output value, you quickly to the conclusion that you need APP not watch you. Habs then but made you plenty of time, it is a holiday.
I quickly saw that there is no problem, re-create and adapt the week expenditure categories. So everything you need.
I would have preferred my expenses entered and saw the sum of expenditure, but here's a different approach.
A pity, I find that you can not change the text existing categories so that you too German. If you want you can delete sue and collect new in German. Is dannhakt more effort.
I will try it mnsl and capture my travel expenses so that I can quickly calculate on hand an output specification.
How useful is the APP, me remains and any other leave to try it and evaluate for themselves.
The app promises to at least nothing that was not working!
