iPhone 4 problem

Hello, I have been using LapTimer Rookie with a Dual XGPS150 on an old iPhone 4 (ios 7.1.2). I installed Dyno, but it will not load. When I launch the app, I see the "Harry's GPS Suite" screen, then the screen goes back to my home screen without launching the app. LapTimer still works. Please advise...
