iPhone app Sonar Ruler

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! <<
