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! <<
Ϟ GIZMODO.com:
"that's a damned neat trick for a phone to be able to do."
Ϟ 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.

Customer Reviews
This ruler is very accurate
To all those people who have first gen iPhones leaving 1-star reviews: THIS APP ISN'T MADE FOR YOUR PHONE!! The first gen iPhone's microphone isn't nearly as good as those in the 3G and 3GS. It is not as sensitive to various frequencies.
I moved into a new apartment a few days ago and this app has worked great. It measures rooms to within a couple inches, which is good enough for positioning furniture. I checked the values with a real tape measure. My wife is amazed. Just make sure you watch the intro video to calibrate your device before using and you're good to go.
What these developers were able to achieve on the iPhone really demonstrates the capability of this platform while also capturing the spirit of innovation that, in my opinion, is what make Apple products great. Their drive and determination to do the seemingly impossible is amazing to me. My freaking cell phone is now a tape measure. For real. Like a bat or dolphin. It's insane. I love science.
Awesome Concept
What a neat idea, I showed this to my kids to explain to them how sound waves travel through the air. Great 'real world' science stuff!
its like having a lab in hand
its a little tricky to use and i had to practice for a bit with how to cup my hand to make the optimal sound, but once i got the hang of it i found it very accurate
