App Description
Catch anyone who tries to unlock your phone — with video and location evidence
🔐 PROTECT YOUR PHONE
Lockwatch emails you photo or video evidence and your phone's location when someone tries to unlock your phone with the wrong PIN, password or pattern.
Choose photos or a 20-second video clip. Lockwatch sends the evidence to your email so you can quickly see what happened.
Lockwatch can also alert you after your phone powers on or restarts, or when a SIM card is changed.

⚙️ FEATURES
Failed unlock alerts
• Detects failed unlock attempts on your existing Android lock screen
• Captures photos or a 20-second video clip of the intruder
• Emails the evidence along with your phone's location
• Cancels the alert if the correct code is entered within 10 seconds, so a simple mistype will not send an email
SIM and power-on alerts
• Detects SIM changes and emails the location with new SIM details
• Emails location immediately after power-on or restart, before the phone is unlocked
History and reliability
• Saves alert history in the app so you can view, share or delete past alerts
• Automatically retries sending alerts when mobile data or Wi-Fi becomes available
• Stays lightweight by only reacting to key security events, so it will not drain your battery
ℹ️ NOTES
• Lockwatch only triggers when an unlock attempt contains at least four digits, password characters or pattern dots.
• This app uses the Device Administrator permission to monitor screen unlock attempts. Lockwatch will never use this permission to wipe your phone.
