Duper 앱
Duper lets you remotely control your Android phone using simple SMS commands — no internet connection, no account, no server.Send "duper ring" to make your phone ring at maximum volume with the flashlight blinking, even in silent mode. Useful when you've lost your phone nearby.
Send "duper locate" to receive your GPS coordinates by SMS at regular intervals. Useful in an emergency or when you lend your phone to someone.
Features:
• Ring with flash, bypasses silent mode
• GPS location tracking via SMS
• Both modes stop when the phone is unlocked
• Configurable prefix, password, duration, and interval
• Custom ringtone support
• Works entirely offline over SMS
• No account, no cloud, no tracking
The prefix and optional password are configurable so only people who know them can trigger commands.
