My niece has started Year 7 and she has an Iphone 5. She showed me 'Screen Time' on Iphone and my brother can control her usage, times, what apps she has access to. Much of what I thought Family Zone does, all for free. Is Family Zone necessary on an Iphone if 'Screen Time' is used? Is it mainly for Android devices?
