For iPhone/iPad/iOsCheck out their quite easy and powerful content restrictions.
Suggestion: Have someone else have the password (or half and half with a spouse) and do the following:
Lock installing apps + remove browser + add apps you need (possible rules: no games, no sports, no entertainment, etc.).
[Occasionally an app will have a built in browser/or need to access a certain website - just go back in to settings (with password) and add that website].
There is time restrictions and more features too.
