Whats new in Sonar Ruler v1.21

4 things about Sonar Ruler

1. It sends a short pulse from the speaker and measures how long that pulse takes to bounce off of something and return to the phone.
2. If you're a teacher, this app is a great way to teach students the principles of sonar, and how sound propagates through air.
3. *This is an experimental app, although it can be quite accurate, any measurements taken should be verified before using them.
4. It then estimates how far away you are.

Crash within 3 seconds

Tried uninstalling and reinstalling on my Android 6 several times but the program exits after 3 seconds every time. Would have been interested to "experiment".
