AppLock Ultra
The privacy-focused app locker for Android — lock apps with PIN, pattern, or fingerprint.
Lock any app and keep snoopers out
AppLock Ultra is an app lock for Android that puts you in control of who can open your apps. Hand your phone to a friend, lend it to a family member, or leave it on a desk — your WhatsApp, gallery, banking apps, and settings stay protected behind a PIN, pattern, or fingerprint gate. Unlike bloated security suites, AppLock Ultra does one job and does it without draining your battery.
App lockers have become essential as phones hold more of our private lives. Whether you want to lock WhatsApp, hide the gallery from kids, or stop someone from changing your settings, AppLock Ultra lets you protect each app individually with its own unlock method.
Key features
- Multiple unlock methods — choose a PIN, a pattern lock, or biometric fingerprint unlock per app.
- Intruder selfie — the front camera quietly snaps anyone who enters a wrong password, so you catch snoopers.
- Fake cover / disguise — show a fake "app stopped" screen so people don't even realize an app is locked.
- Stealth mode — hide the AppLock icon itself and open it with a secret dial code.
- Built-in vault — store private photos and files away from the main gallery.
- Re-lock on screen off — apps re-lock automatically when the screen turns off, for set-and-forget protection.
What you can lock
Who it's for
Parents who share a phone with kids, professionals who carry sensitive work apps, students living in shared dorms, and anyone who simply wants peace of mind. If you've ever wondered "how do I lock my apps," AppLock Ultra is the answer.
Privacy first
AppLock Ultra works locally on your device. It does not upload your app list, PIN, or photos to any server, and it contains no analytics or ad-tracking SDKs that watch what you do. Your lock settings stay yours.
Frequently asked questions
How do I lock apps with fingerprint on Android?
Install AppLock Ultra, grant the permission it asks for, choose the apps to protect, then enable fingerprint unlock in lock settings. Opening any protected app then prompts you to authenticate with your registered fingerprint.
Which app locker has intruder selfie?
AppLock Ultra captures an intruder selfie with the front camera whenever someone enters a wrong PIN or pattern, so you can see who tried to snoop. The photo is stored privately inside the app's vault.
Is AppLock Ultra free to use?
Yes. AppLock Ultra is free to download and use, with core app locking, pattern/PIN, and intruder selfie features available at no cost. Premium cosmetic options may be offered, but the core protection is free.
Can I lock WhatsApp, Gallery, and banking apps?
Yes. You can lock any installed app individually — WhatsApp, your photo Gallery, banking apps, Settings, and the Play Store — each with its own unlock method.
Does AppLock Ultra drain my battery?
No. AppLock Ultra is battery-friendly: it only activates when you open a locked app, instead of running a heavy continuous background service.
