Crashes and loses all of your work – Easy Chart Review

This app crashes frequently (I'm on an iPhone 4S) and loses all of your work. If you don't remember to stop working and exit the current chart to go back to main menu every few minutes, then you lose all of your work. For number crunchers, this is a tragic and aggravating theft of valuable time and effort. Also, you cannot edit the right hand number field but rather if you even click on it it deletes whatever value was in there so you can't see what number was just in it. This is frustrating even when you intended to click on it to change it but it is especially damaging if your finger happens to accidentally touch the right side of the screen.
