Most kids brush for 45 seconds and miss the same spots nightly. Brushee turns that into a game they actually finish.
The front camera guides the full 2-minute routine - four areas, 30 seconds each, then chewing surfaces and tongue - with a little monster whose 16 teeth light up as each area gets clean.
No smart toothbrush, no fake "brushing score" (cameras can't verify that honestly), and nothing leaves the phone: no account, no cloud, no ads, no internet permission.
