Tobe (活着呢) is a minimalist, proactive safety monitoring application for Android. In a world where we often live alone or travel solo, "Tobe" acts as a digital silent guardian. It ensures that if you are unresponsive for a critical period, help is on the way.
- Passive Activity Sensing: Automatically refreshes your "Safe" status when you unlock your phone. No manual action needed for daily use.
- Manual Check-in: A large, satisfying button for those who want to actively say "I'm okay."
- Inactivity Countdown: Tracks the duration since your last activity. If the threshold is exceeded, it prepares to notify your emergency contacts.
- Emergency Automation: Automatically sends SOS SMS messages to pre-defined contacts if you become unreachable.
- Local First: All activity monitoring happens on-device.
- Permission Transparency: Requires SMS (for SOS) and Notification access.
- Download the latest APK from Releases.
- Install on your Android device.
- Grant necessary permissions: SMS, Notifications, and Ignore Battery Optimization (crucial for background monitoring).
- Set your check-in interval and emergency contact in Settings.
