One tap to lock, one tap to unlock. Use it as an app protector, a privacy lock for sensitive apps, or a parental control tool to keep children out of apps they shouldn't access. Perfect for keeping your private photos, secret chats, and personal data hidden from prying eyes.
🔐 Smart security
• Stealth mode — hide pattern dots so no one can watch you draw. Invisible pattern lock keeps your password safe from shoulder surfers
• Lock App Lock itself — prevent others from changing your security settings or disabling protection
• Auto-start on boot — protection resumes automatically after every restart. No need to reopen the app
• Real-time guard — locked apps are challenged with a password screen instantly when opened
🎨 Beautiful and personal
• Dynamic colors — each lock screen adapts to the app's icon colors
• Dark, light, or system theme — follows your preference automatically
• Sound and vibration — tactile and audible feedback on every interaction
• Pin favorites — swipe to pin apps to the top for quick management
⚡ Lightweight
Runs quietly in the background. Minimal battery and memory usage. No slowdowns, no interference with other apps. A secure, reliable app locker you can trust every day.
🔒 100% offline privacy
All credentials and passwords stay on your device. Face recognition uses an embedded AI model — no photos, no biometric data, and no information of any kind is sent to external servers. No account required, no sign-up, no cloud storage. Your privacy is not a feature, it is the default.
