Money app not working

I just spent $4.99 on this because it looked exactly like what I wanted: a simple way to record my daily expenditures. I cannot go back to yesterday without without erasing todays entries and there is no "next" once I enter something. When I went to the app store to start over and ask for support the gym app appeared and that is all I could get, was the preview. I want to be able to save my entries and edit them if necessary and see the totals each week or month. Where are the instructions?
