Custom timers dont save

This app is great and fits my needs perfectly only it doesnt save the timers I create, which I spent lots of time on putting together. When you leave the app and go into something else and come back to it it goes back to default with only the example timers available and my custom timers are gone. This would be a 4-5 star review if not for this problem.
