A simple tool to prevent app access with PIN, pattern or password lock.

▶

Features & Capabilities

App Locker protects your Android apps with a PIN, pattern or password. Lock Facebook, WhatsApp, Gallery, Messenger, Instagram, SMS, Contacts, Gmail, Settings, incoming calls and any other app you choose. Supports Android 5.0 and up and includes advanced options to prevent uninstalling or disabling the locker by activating device admin and locking the Settings app.

Privacy-first design: the extension does not request dangerous permissions (Location, Contacts, SMS, Storage) and uses only the Accessibility service to detect app access — it does not send your data to remote servers. If you forget your lock, you can clear app data or reinstall (note: clearing data may be blocked if device admin and Settings lock are enabled). For demos and support, contact thesimpleapps.dev@gmail.com.

User Reviews

Users praise App Locker for its effective and simple app protection, absence of ads, and its fingerprint unlock feature. It closes common security loopholes, making it one of the better applocks available. However, multiple users report that locked apps' content can still be seen on the recent apps screen, which is a significant privacy flaw. Other common complaints include inability to lock some system apps, no protection against uninstalling the app itself, occasional problems with biometrics, and missing advanced features like intruder snapshots.

Pros

Effectively protects apps and restricts access, including closing common loopholes like phone Settings and Accessibility options.
Simple, easy to use, and has a clean, beautiful interface without ads.
Supports fingerprint unlocking as a security feature (recently added).
Allows users to control app locking frequency and has variable password length options.
Works well for parental control to restrict children's access to certain apps.

Cons

Content of locked apps is still visible on the recent apps screen, posing a privacy risk and requiring a fix.
Cannot lock certain system apps such as package installer and quickstep launcher.
Does not prevent the app itself from being uninstalled, limiting security effectiveness.
Some issues with biometric authentication errors (too many attempts) and occasional repeated pattern entry needed to unlock.
Lacks some advanced features like intruder photo snapshots and compatibility issues with secure startup due to use of Accessibility services.

Recent reviews

Getting error: "Couldn't use biometrics (Too many attempts, try lock instead)". Set "Reset Lock timers" from app but still getting the error. Tried restarting the app too but still the same issue. Please help.
