Description
Show full descriptionShow less
Lock any app with a PIN, pattern or fingerprint, hide private photos in a vault, hide what apps show in your notifications, and set daily limits on the apps that eat your time. App Lock keeps your chats, gallery and banking apps private.
🔒 LOCK APPS IN ONE TAP
• Lock chats, gallery, photos, banking, social and shopping apps
• Unlock with a PIN, pattern or fingerprint
• Lock whole groups at once: social, finance or games
• Recommended apps: see which private apps are still unlocked
• Relock right away, when the screen turns off, or after a few minutes
🔕 QUIET: HIDE NOTIFICATIONS
• Hide what any app shows in notifications, locked or not: you only see that something arrived
• App Lock asks when you lock an app if you want its notifications hidden too
• Get hidden notifications silently, in an hourly digest or once a day at your time (Premium)
⏱️ FOCUS: APP LIMITS & SCREEN TIME
• Daily time limits, up to 6 hours, for the apps that pull you in
• See today's screen time on your limited apps
• Limit how often an app opens, or add a 5-second pause before it opens (Premium)
🗂️ PRIVATE PHOTO VAULT
• Hide photos, videos, documents and audio in an encrypted vault
• Vault files open only inside App Lock, not in your gallery
🕵️ CATCH SNOOPERS
• Intruder selfie: a photo of anyone who enters a wrong PIN or pattern
• Email alerts with the photo and time (Premium)
• Spy alarm after repeated wrong attempts (Premium)
🎨 A LOCK SCREEN THAT FEELS LIKE YOURS
• Three themes: Night, Light and Signal
• Your own lock color and wallpaper (Premium)
🏠 SMART UNLOCK
• Skip the lock on trusted Wi-Fi or Bluetooth, like at home or in your car
🎭 MORE PRIVACY TOOLS
• Fake crash screen to fool snoopers
• Private browser that clears history when you leave
• Lock schedules, usage statistics and uninstall protection
FREE AND PREMIUM
App Lock is free with ads: lock as many apps as you like, hide one app's notifications, limit one app and keep 5 files in the vault. Premium is a one-time purchase that removes ads and unlocks every feature.
PERMISSIONS AND PRIVACY
App Lock uses Usage Access to see when a locked app opens, Display over other apps to show the lock screen, and Notification access only to hide the notifications you choose. Device admin is used only for the optional uninstall protection. Your data stays on your phone.
