Kids earn rewards with a fun 2-minute timer. Ticko turns tooth brushing into a game with cartoons, streaks and treasure chests. Free app for ages 3–9.

Most tooth brushing apps are timers with a progress bar. Ticko is built around a story. A robot astronaut crash-lands on Earth. His spaceship runs on clean teeth. Kids charge his battery by brushing for 2 minutes — and every session unlocks the next chapter of his adventure. No ads, no subscription. Episode 1 is free (10 days of content). Episodes 2 and 3 are one-time purchases. Built solo, shipped on iOS and Android.
