For grown-ups
KnockTots turns a knock into a code. Each knock is a pattern of quick and slow gaps, and the door opens only when the pattern matches. That is the big idea behind passwords and secret codes.
Your child copies the animals' knocks first. Then the family makes up its own secret knock. The app keeps only the pattern of quick and slow gaps on this device, nothing else, and no microphone is ever used.
Then try it at a real door: one person knocks the family knock, the other listens. Is it really you?
What it never does
- No accounts, no ads, no tracking — anything kept stays on this device.
- No streaks, timers to beat, points to chase or leaderboards.
- No chat, and nothing anyone types is sent anywhere.
