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.

No limit 15 min 30 min 45 min 60 min
  • Counts foreground time only — never the background.
  • Never interrupts a puzzle already in progress.
  • Shows what your child practised this week, and the thinking skill each game builds.
  • Stays on the device. No account, no upload.

27 games. Twenty-seven ways to think.

Logic, numbers, spatial reasoning, coding, rhythm, words, memory and geography. Most generate a fresh puzzle every time you play.

    One purchase. Yours to keep.
