For grown-ups

A daily limit that counts honestly.

Most limits bill you for time your child wasn't playing — the app sits in the background and the clock keeps running, so thirty minutes is gone in ten. Doozle counts only the time it is open and on screen. A locked screen, a phone call, or another app in front is never charged against the limit.

And reaching the limit never snatches away a puzzle in progress. It waits for the next one, and says so kindly.

Daily play limit

Off by default. A grown-up sets it behind a press-and-hold a young child won't get past.
