Wont install under iOS 9 – Battery Watch for Apple Watch Review

I have tried on two devices and it comes up with a dialog box saying this app can not be installed at this time. I had issues with it after updating to OS 9 so I deleted it and then it would not reinstall. Same issue on iPhone and iPad. LOVED this on my apple watch under iOS 8. Reported to Apple and they said to contact the developer.
