Avoid this update!!!

I loved the PanoBike App until I installed the current version (2.2.3) on my iPhone 5c running iOS 8.1.2. When I tap the icon the Pano app start screen momentarily appears then the phone goes back to the home screen. If I double click the home button I can see that the app is running but I can not access it. This update completely rendered the app unusable. Please fix this or revert back to the prior version.
