App wont work on any iOS that is lower than 9.0. That is not a good business move and just installed the app and wont ever use again.
Im on iOS 8.4 and is the most stable app and will not upgrade and you shouldnt force your customers to. Fix your app for iOS 8 users and I will change my star review back to 5 stars.
