Works as described, but hogs battery – Focus — Screen-Free Driving Review

This app works as described and is great at encouraging you not to use your phone while driving. My biggest complaint is that it is a major battery hog whether you spend time driving or not. It burns up my battery too fast for me to be able to keep it installed and running...my phone is unusable. (iPhone 6 iOS 9)
