🔐 LOCKWATCHER: SEE WHO TRIED TO UNLOCK YOUR PHONE
Ever wondered who touched your phone? Lockwatcher secretly activates when someone enters the wrong PIN, password, or pattern. It instantly captures a front-camera selfie, records the GPS location, and emails you the evidence—so you can see exactly who tried to get in. Perfect for catching snoopers, curious friends, or phone thieves.
Unlike basic security apps, Lockwatcher combines the reliability of classic intruder detection with advanced anti-theft tools. It is the ultimate Cerberus alternative, completely free to use, with powerful premium upgrades.
🥳 FREE PROTECTION (Always Included)
Detects Wrong Attempts: Triggers on incorrect PIN, password, and pattern unlocks.
Intruder Selfie: Silently captures a front-camera photo.
GPS Location: Emails you the exact location of your phone at the time of access.
Works with Your Lock Screen: Uses your existing Android lock screen—no setup changes needed.
No False Alarms: Cancels the alert if the correct code is entered within 10 seconds (so a simple mistype won't spam your email).
100% Ad-Free: Zero ads in the free version.
🚀 UPGRADE TO PREMIUM (More Evidence & Control)
🎥 20-Second Video with Sound: Record the intruder in action with full audio for undeniable proof.
📸 Surroundings Snapshot: Captures a photo using the back camera simultaneously, showing you the environment.
📱 SIM Change Alerts: Get an instant location alert with the new SIM details the moment someone swaps your card.
⚡ Power-On Alert: Receive a location alert immediately after your phone restarts—before the phone is even unlocked.
📜 Expanded History: Keep up to 50 alerts in your history log instead of just 5.
🎭 PRO ADVANCED TOOLS (Outsmart Intruders)
Disguised App Icon: Hide the app with a fake icon and name (e.g., "Calculator").
Fake Home Screen: Show a dummy home screen to trick intruders into thinking they got in.
Custom Warning Message: Display a personalized warning to scare off snoopers.
App Lock: Password-protect Lockwatcher itself so intruders can't delete evidence.
Block Shutdown & Airplane Mode (Accessibility): Prevents intruders from turning off your phone or disabling Wi-Fi/mobile data to stop the alert. Experimental feature.
📊 EXCLUSIVE BONUS FEATURES (Not found in Lockwatch or Cerberus)
App Usage Tracker: See exactly which apps were opened after your phone was accessed. Know what the intruder viewed.
"Don't Touch My Phone" Alarm (DTMP): Triggers a loud siren instantly when the phone is picked up from a table or desk—perfect for public places.
🕘 BUILT FOR RELIABLE ALERTS
Auto-Retry: Automatically retries sending alerts when mobile data or Wi-Fi becomes available.
Battery Friendly: Designed to run only when needed, minimizing battery drain.
Offline Support: Saves location data to sync later when internet is restored.
📌 IMPORTANT NOTES
Activation: You must unlock your phone once after a reboot to reactivate the service.
Camera Notification: On Android 13+, a "camera-in-use" notification may appear briefly while capturing.
Compatibility: Not compatible with pop-up cameras or "fingerprint-only" unlock methods (must have PIN/Password/Pattern enabled).
Device Administrator: This app uses the Device Administrator permission solely to monitor screen unlock attempts. Lockwatcher will never use this permission to lock or wipe your phone.
