Make your old smart phone a brick phone. Lock your selected apps behind a PIN and second factor — making it a good first phone or digital detox.
Change what's unlocked any time as they grow up — no need to buy a new device at every stage.
Not just for kids — use it on yourself for a genuine break from the apps you can't put down.
Click into "School," "Bedtime," or any mode automatically, once it's set up.
Use the smartphone already gathering dust — no separate device or contract, and it lasts longer.
Real OS-level blocking, not just a closed app they can find a way round.
A parent PIN backed by a second factor — recovery codes mean you're never locked out for good.
Your school administrator can check your phone is compliant before it goes on site.
