The Bark Watch has real-time location tracking built in. If your child loses their watch, you can find it from your dashboard.
Open up your parent app / dashboard.
Under your child's profile, tap Find Watch.
The watch will ring at full volume (even if it was originally silenced) as long as it's turned on and connected to mobile data or Wi-Fi. If it's turned off, you'll see a message letting you know as well as the last detected location activity of the device.
If you'd like to remotely lock down the device, pause the watch.
