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!

Verdict

The call

The clearest difference is in-app purchases: Sonar at none against BimmerDash's 3. Sonar also leads on ads (none vs shown) and device support (3 vs 1). BimmerDash's advantage is update cadence (every 10 days vs every 6 months). On price there is nothing between them.
