The point of prisons is not just to punish but rather to help “fix” people. Should your app play any role in that? At the moment, money is what keeps patients from spending tons of time on the phone (amongst other things). Can call points be a reward for doing well inside? Perhaps you get extra points when you visit the prison library or if you take classes to learn a craft? Not to complicate your plans, but feels like an opportunity that might help get support from policy makers.
