Has potential, but keeps closing!!

I can see the potential in the app. I was able to get a decent amount of info into the program and am excited about it helping me, but it frequently quits when trying to change things. It is not functioning properly and its very frustrating to lose inputed data becuase of the frequent closing. Would give it a higher rating if it didnt keep closing!! Please help/fix!!!!
