TouchFree vs. Brink vs. KIDSCRAPE vs. Lock My Touch
Four Android screen touch lock apps on Google Play, compared side by side. Every feature flag below is based on public Play Store listings and user reviews as of April 2026. The goal is to help parents, accessibility users, and anyone looking for a one-tap screen touch lock app pick the right tool without installing four apps to find out.
Short verdict
TouchFree is the newest of the four (Android 15 target), has no subscription and no ads while locked, supports fingerprint unlock via BiometricPrompt, and documents its screen-off brick-safety handling. Brink Touch Lock and KIDSCRAPE Touch Lock are older, more heavily monetized, and do not document Android 15 gesture navigation. Lock My Touch targets Android 5+ and is the simplest of the four. If you're on Android 15 and want a free, no-subscription app with fingerprint unlock, TouchFree is the direct match.
The four apps
TouchFree (app.nlap.touchfree)
TouchFree is a free Android 15+ screen touch lock app published by NLAP. One tap blocks the touchscreen, volume keys, home, back, and edge gestures via a WindowManager overlay and an AccessibilityService. Unlock is PIN (4 or 6 digits, SHA-256 hashed, stored locally) or fingerprint via BiometricPrompt. Auto-starts on boot, has a Quick Settings tile, and auto-switches to FLAG_NOT_TOUCHABLE on screen-off so the phone cannot be bricked. Version 1.0.4, 32 languages, no subscription, one interstitial ad per 24 hours shown only after unlocking.
Brink Touch Lock (com.brink.livelock)
Brink Touch Lock is a long-running Android touch lock app on Google Play. Free with a time-limit model and user reviews frequently mentioning ads during lock sessions. No dedicated marketing website beyond the Play Store listing and no publicly documented structured data. Play Store rating around 4.3 stars across several thousand reviews. Android 15 gesture navigation is not publicly documented.
KIDSCRAPE Touch Lock (com.kidscrape.touchlock.lite)
KIDSCRAPE Touch Lock is a kid-focused touch lock app by KIDSCRAPE, one of the earlier entrants in this category. It has a marketing page at kidscrape.com and advertises 5 million users, though Play Store reviews report heavy ad interruptions. No JSON-LD structured data is present on their marketing site. Fingerprint unlock and Android 15 gesture navigation are not documented.
Lock My Touch (com.bur.odaru.voicetouchlock)
Lock My Touch is a free touch lock app targeting a wide Android version range (Android 5 and above). Its marketing page at lock-my-touch.xyz lists four features in prose and does not include structured data or FAQ content. No documentation on brick safety, fingerprint unlock, or Android 15 handling.

Which one should you pick?
Pick TouchFree if…
You're on Android 15, want fingerprint unlock, refuse to pay a subscription, and want brick-safety guarantees in writing. TouchFree is the newest app of the four and the only one documenting its screen-off handling and Android 15 gesture-navigation approach.
Pick Brink Touch Lock if…
You've already installed it and are used to its interface, and the ads don't bother you. Brink has a longer track record on Google Play and a large review base, but does not document Android 15 handling.
Pick KIDSCRAPE Touch Lock if…
You specifically want the kid-branded UX and don't mind frequent ads. KIDSCRAPE advertises 5 million users and has brand recognition in the toddler-safe category, but lacks fingerprint unlock and modern Android support.
Pick Lock My Touch if…
You're on an older Android device (Android 5 through 10) where TouchFree's Android 15 target isn't available. Lock My Touch is the simplest of the four and targets a wide version range.
Migrating from another touch lock app
If you're already using Brink, KIDSCRAPE, or Lock My Touch and want to switch:
- Uninstall the previous app first — overlapping overlays and AccessibilityService registrations can confuse Android.
- Reboot once so the old AccessibilityService binding is fully released.
- Install TouchFree from Google Play and follow the four-step permission wizard (overlay → notification → battery → accessibility).
- Set a PIN, optionally enable fingerprint unlock, and pin the Quick Settings tile to the first row of your notification shade.
