About

LockUrApp

Features
Read full description

LockUrApp is your private vault. Add shortcuts to the apps you want to keep private, and reveal them only after unlocking with Face ID, Touch ID, or a 6-digit PIN. Your everyday apps stay hidden behind a lock only you can open. WHY APPLOCKER • Face ID / Touch ID / PIN — your vault opens only for you. • A clean, private launcher for the apps you'd rather keep to yourself. • Everything stays on your device. No account, no sign-up. PRIVACY & SECURITY FEATURES • Face ID & Touch ID — instant biometric unlock, with a 6-digit PIN fallback. • Decoy PIN — set a second PIN that opens a harmless empty vault, so a curious onlooker sees nothing. • Intruder Selfie — after repeated wrong PIN attempts, AppLocker can quietly snap a front-camera photo so you know who tried to get in. • Guard Mode — turn your phone into a tripwire: if someone moves or unlocks it, an alarm sounds until the correct PIN is entered. • PIN Lockout — too many wrong attempts temporarily disables entry (1, 5, or 30 minutes). • Activity Logs — review guard alerts and a history of what was opened, and when. MAKE IT YOURS • Custom icon and color for every item in your vault. • Drag to reorder your apps. • Scheduled lock — keep certain apps locked during set hours of the day. PRIVATE BY DESIGN Your vault, PIN, and settings never leave your device. There are no accounts and we don't collect your personal data. The app is free and supported by ads (Google AdMob); see our Privacy Policy for details. HOW IT WORKS (please read) iOS does not allow any app to block other apps from opening directly from the Home Screen. AppLocker is a private, protected launcher: the shortcuts inside your vault can only be revealed and opened after you authenticate. It's the same model used by app-locker apps on the App Store. Download LockUrApp and keep your private apps private. ## What's New (v1.0) First release of LockUrApp — a private vault for your apps with Face ID/PIN, decoy vault, intruder selfie, guard alarm, scheduled lock, and activity logs.
