Applock Pro - App Lock & Guard

Your private photos and messages are only a single tap away from prying eyes. Applock Pro - App Lock & Guard by Eywin Apps gives you precise, hardware-accelerated control over who accesses your most sensitive applications and system settings.

This utility operates as a dedicated security layer that intercepts app launches and enforces authentication via PIN, pattern, or fingerprint. It does not rely on Android's built-in screen lock, meaning you can keep your device unlocked while still protecting individual apps like banking, messaging, or photo galleries. The app runs as a background service with minimal battery drain, using Android's accessibility API to detect foreground app changes in real time.

Core locking capabilities include:
- Hide app icons from launcher after locking
- Set per-app lock timeout (immediate, 30 seconds, or 5 minutes)
- Enable fingerprint unlock on devices with a compatible sensor
- Create multiple lock profiles for work, home, or guest modes

Intruder detection system captures and stores:
- Front-facing camera photo on failed unlock attempts
- Timestamp and duration of each intruder session
- Location data (if GPS is enabled) when a wrong pattern is entered
- Failed attempt counter with lockout after 5 consecutive failures

Advanced privacy tools include:
- Decoy password that opens a fake, empty app drawer
- Vault for hiding photos, videos, and documents behind the lock screen
- Wi-Fi and Bluetooth auto-lock triggers when leaving trusted networks
- Schedule-based locking (e.g., lock all games during work hours 9 AM–5 PM)

• Pattern lock with 3×3, 4×4, or 5×5 grid sizes
• PIN lock with 4–16 digit custom length
• Fingerprint lock for devices with Android Marshmallow or newer
• Custom lock screen wallpaper per app or profile

Performance optimizations prevent slowdowns:
- Lock screen renders in under 200 milliseconds
- Background service uses less than 15 MB RAM
- No persistent notification after initial setup
- Adaptive battery mode suspends lock checks when device is idle

Consider downloading Applock Pro - App Lock & Guard if you share your device with family, coworkers, or frequently lend your phone. You might enjoy the intruder selfie feature that silently documents anyone attempting to crack your pattern. We suggest trying the decoy password mode first—it's the fastest way to test the app's core security without affecting your normal usage.
