The device stays in the bag.
Keep the phone, watch or tracker in the swim bag or locker, not in the water. Most location devices are not made for swimming, and GPS does not work underwater.
An arrival you can see.
Save the pool as a Place. An arrival alert tells you the device reached the pool; a departure alert tells you it left. Indoors, the position may be approximate.
Not a water-safety device.
Navioa cannot tell you anything about what happens in the pool. Supervision by coaches and lifeguards is what keeps swimmers safe. Use Navioa for the trip there and back.
A simple pickup plan.
Agree where your child waits after practice and what to do if you’re running late. Check the update time on the map before you leave.
