This tool is designed to help people to track your kids.
FIrst of all, you just need an old phone with 【Children Protector】app installed. Then just put the phone in kids backpack.
You can use the app to track where your kids are.
In the future, we will design 【Elder Protector】and 【Car Protector】and let the 【Family Protector】be able to track all kids, parents, and cars.
