Interferes with iPhone 6

This app was purchased several months ago, worked great, I loved it. I could put it on the face of the Apple Watch and just activate it for sleep and waking, easy. But 2 updates ago it started to interfere with other apps. Sometimes it would download the days report 2 or 3 times. It would also freeze, and then the phone would be grayed out and nothing would be active. Then you need to lock and unlock the phone to make it active again. I ended up removing the app.
