Not compatible with IOS 11 (I-Phone) – Islamic Compass Free - Prayer Times and Adhan Alarm Review

I have been happily using this wonderful app for years, and now my iPhone, now iOS 11, gives an error message that this app needs to be updated by the developer. I believe I purchased the $3.99 version (can’t remember). I tried contacting the developer w no luck. Any suggestions would be greatly appreciated. .
