Everything App Lock can do
Lock any app, choose exactly how and when it locks, and catch anyone who tries to get past it.
Intruder selfie
App Lock silently takes a front-camera photo when someone enters the wrong PIN, pattern or knock code on a locked app. See who tried, and when.
How it works →fake crash app lockFake crash screen
Fake Cover shows a convincing “has stopped working” error instead of a lock screen, so snoopers give up. Long-press OK to reveal your real lock.
How it works →hide app lock iconHide the App Lock icon
Icon Camouflage swaps App Lock's launcher icon and name for a Calculator, Compass, Music or Contacts icon, so nobody knows your apps are locked.
How it works →hide notifications androidNotification privacy
Hide message previews from locked apps and keep a private, on-device copy of notifications you receive, even after the sender deletes the message.
How it works →knock code app lockKnock code, PIN, pattern & fingerprint
Lock apps with a knock code, 4-digit PIN, pattern, fingerprint or face unlock. Add a shuffled keypad and hidden pattern so nobody can shoulder-surf.
How it works →app lock scheduleSchedules, groups & delay lock
Lock apps only during the hours you choose, lock a whole group of apps in one tap, and skip re-unlocking for 30 seconds when you switch apps.
