The Amazing New Sonar Ruler is an experimental app that uses echoes to measure distances with your iPhone!* It uses the same principles that dolphins use to find food! *
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. It then estimates how far away you are.

"that's a damned neat trick for a phone to be able to do."
Currently the number one app in Denmark! Heck yes!
Features:
* Sonic distance measurement up to 60 feet
* Set Units to feet, inches, or meters
* Custom saved settings for measuring in different environments
If you're a teacher, this app is a great way to teach students the principles of sonar, and how sound propagates through air.

*This is an experimental app, although it can be quite accurate, any measurements taken should be verified before using them.
