Kids Screen Time Lock & Timer

Kaizen-Apps

About this app

📵 The phone was built by geniuses to never be put down. You can't out-willpower that — but you CAN set a hard limit.

Kaizen Timer is the dead-simple screen-time app for parents of young kids. Set a time, hand over the phone, walk away. When time's up, the phone locks itself full-screen — and only YOUR unlock reopens it. No dashboards, no accounts, no setup marathon.

Best of all, the timer becomes the "bad guy," not you. "20 minutes" means 20 minutes, every time — so the end-of-screen-time meltdown is the phone's problem, not a fight with mum or dad.

WHY PARENTS LOVE KAIZEN TIMER
🔒 Can't be bypassed — a real full-screen lock. Switching apps, pressing home, swiping it away won't get past it. Built for small kids.
🔇 Silences the content too — optionally mutes YouTube, games and music the moment it locks, and restores sound when you unlock.
⭐ Gentle warnings — friendly alerts at 10, 3 and 1 minute left, so kids wrap up calmly instead of a sudden cut-off.
🔑 Parent-only unlock — opens with your phone's fingerprint/face/PIN, or set a separate 4-digit PIN. Kids can't get past it.
📊 Screen-time stats — see how long the phone's been used and stay in charge.

NO ADS. NO TRACKING. FULLY OFFLINE.
Most "screen time" apps are bloated, ad-filled or quietly harvesting your family's data. Kaizen Timer is the opposite: no ads, no accounts, no analytics — nothing about your child ever leaves the phone.

TAKE THE SCREEN AWAY, AND WATCH WHAT HAPPENS
Cap the phone and kids fill the gap — with play, drawing, running, and the boredom that turns into imagination. You're not taking something away; you're giving back their focus, their patience, their childhood.

HOW IT WORKS
1. Pick a limit — 20 minutes, an hour, your call.
2. Hand over the phone. It counts down with gentle warnings.
3. Time's up: it locks full-screen and goes quiet. You hold the key.

Free to start (sessions up to 9 minutes) with the full lock, unlock, warnings, audio-silence and stats. Upgrade once to Pro for any time limit — a one-time purchase, no subscription, ever.

Built by a parent who needed it — and runs on the phones in our house every day. Works on Android 8.0 and up.

Give your child their attention back. Set your first timer in three seconds.
