I use iPads at worked which are locked within a specific app. It's incredibly reliable and virtually never falters. These also get data through wifi and are never turned off.
On IoS within Settings>Accessibility>Guided Access you can lock the device to an app and control what all the buttons and controls do. We lock the device so even if the home button is pressed (or any combination), it won't work and all gestures to leave the app are disabled .
Edit: Just to confirm, this is for students with severe learning needs.
