About this app

This app is recommended for those who go hiking.
It notifies you of your location using a bear bell and a light.

Here are some examples of how it can be used. Please give it a try.
1. Launch the app and start the "Bell Sound" feature.
2. Press the lock button to lock the screen. Then put the device in your pocket.
The bell will continue to ring at the interval and volume you set.
3. If you suddenly feel anxious, start the "SOS Sound."
4. The light will turn on at the same time as the emergency sound (thunder) sounds.
5. The emergency sound and light will let people a little further away know your location.
