Google Family Link is genuinely excellent — it's free, and it covers ongoing supervision, app limits, location, bedtime and content filtering across your child's whole device. But it's built around Google accounts and whole-day schedules, and sometimes that's more than you need for one simple moment: handing your young child the phone for a set number of minutes and having it lock when time's up. Kaizen Timer does exactly that — a focused, no-account, one-tap session lock for Android. Use it alongside Family Link, or on its own.
A fair, honest look at two tools that solve different problems — Family Link for full, ongoing supervision, Kaizen Timer for one focused moment. Many families happily use both.
| Feature | Google Family Link | Kaizen Timer |
|---|---|---|
| Price | Free | Free up to 9-min sessions · Pro $21 one-time (unlimited length) |
| Scope | Full ongoing supervision suite — screen-time limits, app management, location, content filters, bedtime | A single session lock — set the minutes, hand over, it locks |
| Accounts | Google account for both parent & child | None — no account of any kind |
| Setup | More steps — accounts, supervision link, device setup | One tap — install, set minutes, hand over |
| Best for | Long-term supervision, app & content management, knowing where your child is | The immediate "hand the phone over for N minutes, then lock" moment |
| Hard immediate full-screen lock on a handed-over phone | Not its focus — built around schedules & daily limits | Yes — full-screen lock at zero, parent unlock only, no app-switch or swipe bypass |
| App approval, limits & content filtering | Yes — approve apps, set per-app limits, filter content | No — it's just a session timer, not an app/content manager |
| Location | Yes — see your child's device location | No — out of scope for a session timer |
| Data | Google account & cloud (reasonable for what it does) | Zero data collection — fully offline, stats stay on the device |
Google Family Link is a trademark of Google LLC and is not affiliated with Kaizen Apps. Family Link is a free, comprehensive parental-supervision service and does far more than Kaizen Timer; the notes above reflect its widely described, account-based feature set.

If you're searching for a "Google Family Link alternative," it's worth saying clearly up front: Family Link is excellent, and it's free. For most families looking for ongoing, account-based supervision of a child's Android phone, it's the obvious choice and we'd genuinely recommend it. It manages screen-time limits, app approval and per-app limits, location, bedtime and downtime, and content filtering — all from the parent's phone, across the child's whole device and whole day. That breadth is exactly its strength.
Kaizen Timer isn't trying to compete with any of that. It does one small thing, on purpose, and does it well: you set the number of minutes, hand the phone to your child, and when the time runs out the phone locks full-screen until a parent unlocks it. That's the whole job. So the honest answer to "which should I use?" is usually both, for different moments — and sometimes just Kaizen Timer, if a simple session lock is all you actually need right now.
We want to be fair, so let's give Family Link its due — because it earns it:
If those are the things you need, Family Link is the right tool, and Kaizen Timer is happy to sit alongside it rather than replace it.
Here's the gap Kaizen Timer fills. Family Link is account-based and schedule-based — wonderful for the long game, but it isn't really built for the very common moment of: "You can watch for 20 minutes, here's the phone." For that one hand-over, you may not want to set up a Google account for a young child, link supervision and configure whole-day schedules. You just want a hard limit on this session, right now. Kaizen Timer is built for exactly that:
For a lot of families, the best setup isn't one or the other. Keep Google Family Link for the big picture — the ongoing limits, app and content management, bedtime and location that protect your child across their whole device. Then reach for Kaizen Timer for the specific hand-over moment, where you want a hard, immediate session lock without opening a dashboard or worrying about accounts. The two don't conflict; they cover different needs. Family Link sets the boundaries for the day; Kaizen Timer enforces the limit on this 20 minutes.
Not exactly — and it doesn't try to be. Family Link is a free, comprehensive supervision service handling screen-time limits, app approval, location, bedtime and content filtering across your child's whole device. Kaizen Timer does one focused thing: set the minutes, hand the phone over, and at zero it locks full-screen until a parent unlocks it. Many parents use both.
No. Unlike Family Link, which is built around Google accounts for parent and child, Kaizen Timer needs no account of any kind — useful for a young child with no account, a shared family phone, or a quick hand-over.
For young kids — no. At zero, a full-screen overlay is drawn over every app, and the timer is tracked independently, so swiping it from recents, pressing home or opening other apps doesn't stop it. It still appears if the phone reboots mid-session, and only your unlock (phone unlock or a custom PIN) reopens it. It's built for small children, not tech-savvy teenagers.
Family Link is completely free, so this isn't about price. Kaizen Timer is free too for sessions up to 9 minutes, with the full lock, parent unlock, warnings and stats. Pro is a one-time $21 for unlimited session length and lifetime updates — no subscription, with a 3-day refund. You'd only pay if you want longer sessions.
No. Zero analytics, zero cloud sync, zero tracking — screen-time stats stay on the device only. Family Link, by design, ties supervision to your Google account and cloud, a reasonable trade-off for everything it does but a different model from Kaizen Timer's fully offline approach.
Google Family Link is excellent for ongoing, account-based supervision — and it's free. For the simple moment of handing your young child the phone for a set number of minutes and having it lock, add Kaizen Timer: no account, one tap, a lock that holds, and zero data collection.
