We have had problems with the app giving us low battery warnings after the watch has already died and the GPS shows kids last location as somewhere other than where it is physically. Here is an idea…let’s introduce a low battery warning on the phone or watch. Starting at 20% it beeps once every 5 minutes and at 10% the beep gets louder every 3 minutes. I would buy my kids an extra charger or battery pack for their backpacks so they can charge their device while being mobile. This is a problem that parents who are trying to get their kids to be responsible with expensive devices can solve if they know where the noise is coming from.
