## What is Sonar?

Imagine yourself in the unfortunate situation where you are trapped under debris after an earthquake or a typhoon disaster or buried under meters of snow as a result of an avalanche. Your watch will most possibly be the only, within reach of access to press a button. Press it and your phone will be transmitting a loud Morse code, as an alarm, indicating your altitude or depth in case rescue is close looking out for you. Simultaneously, an ultrasonic alarm is activated so a K-9 rescue team can listen from bigger distance. As part of your everyday life, you can just use it to locate by sound  your favorite device in home, office and outdoors!

### 3/5 — Confused

*2020-08-30, version 1.2*

So I pressed the alarm button but I don’t think it does anything! Is it the fact that I have an iPad or somethin

### 4/5 — Ok but

*2018-07-13, version 1.2*

Altitude is in meters but there is no m. Should be selectable to ft.

### 3/5 — Needs update

*2016-04-27, version 1.2*

This app doesn't seem to be automatically sending the location every minute as it states it will. Definitely needs update.
