KneeTots
A knee-bouncing rhyme for a grown-up and a little one. Each bounce sings the next line at your own pace; tip back to land the last line. Then the screen rests and the rhyme is yours. Ages 3–5.
▶ Play it nowBuilt for sittings of about 10 minutes on the screen. That is our design budget, not a measurement.

Meet the cast
KneeTots has two friends who love a lap game. Boingle bounces only when you bounce, and Tiptuck waits for the tip at the end.
Boingle
(Hero, a kangaroo joey) - bounces only when your knees bounce, so the rhyme keeps your beat, not its own
Tiptuck
A round tortoise - tips back slowly at the end of every rhyme, because the last line lands only on the tip
