This app promises a lot, and if they could deliver without all the glitches, they would have get a five star rating from me. The glitches are too many to list, but include freezing up on the parent app, rendering it unusable for periods of time unless you turn your phone off and then back on, and seemingly randomly blocking or unblocking apps and allowing some apps to be used past the specified "bed time block". Also, one of my daughters has an iPhone and it is completely useless on her phone. On an apple device, the Screentime app with cause the whole phone to become unusable and glitchy. I can't believe they can even sell this app for iPhones... it is utter crookery. Do NOT get Screentime if you have or plan to get your child an iPhone. However, you can control another device FROM an iPhone only having to deal with the glitches listed at the beginning of this post. Very frustrating, but still useful for Android devices in a "better than nothing" sort of way.
