Slick but not quite there yet
The main things you do in this app for some reason is needlessly complicated. Entering the description then the amount should have a button to advance fields (i.e. a next button) and not require you to click done then tap the other field and then hit done again. Categories would be very useful. Another app, BUDGT, gets these all right, and had CSV export.
