Sonar Ruler is a winner in the Best App Ever Awards - "Most innovative use of iPhone hardware" category!

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.

>> Impress your friends with what this unique app can accomplish using only an iphone! <<

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.

Note: Use with iPads requires some adjustment to the chirp boundaries
