Lock apps with PIN, pattern or fingerprint. Catch intruders, hide notifications
AppLock keeps your private apps, chats and photos away from prying eyes. Lock any app in seconds with a PIN, pattern or fingerprint, and stop worrying when you hand your phone to someone else.
🔒 LOCK ANY APP
• Lock messaging apps, social media, gallery, email, banking apps and settings with one tap
• Unlock with PIN, pattern or fingerprint / face unlock
• New App Detection: AppLock asks you to lock newly installed apps right away
• Recent Apps Lock: lock the recent apps menu so nobody can browse what you opened
📸 INTRUDER SELFIE (SPY CAMERA)
Someone tried to open your apps? AppLock silently takes a photo of anyone who enters the wrong password, so you see who tried to snoop and when.
