I got my kids SyncUp Kids watches recently. They allow my kids to text or call me, my wife or each other. They also have a few very simple features on there to keep them mildly entertained without being too distracting. They also give me alerts when they leave and enter certain areas like home and school, and have an easily scheduleable school mode that turns off all distracting features when they are in school. All in all, they’re pretty good.
