Description

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."

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.

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

Good concept. Not enough polish.

I nabbed this app on an impulse buy after seeing it on a particular website. It is sadly, not more than a novelty at this time.

A short video plays on first launch, leaving you with only the faintest idea how it works. The user interface was unintuitive but detailed.

This app could use a LOT more work into ambient filtering, as it was largely useless due to interference from just about anything. Hopefully, a more concise tutorial and intuitive interface can be worked in. Using an iPhone 3G S

Very accurate

Down to the decimal accuracy. Just point it at a wall and get the distance. Once it is calibrated right it is very accurate!

Could not get it to work at all

I read a bunch of reviews, both good and bad and was fully aware of the fact that this app really falls into the experimental category. But the idea is exceedingly cool and this particular app seemed to be the one to get. As per the author's instructions, I viewed the instructional video and read all of the documentation twice. Nonetheless, I was unable to get the app to work at all. It never gave me an accurate measurement even once. In fact, it never really gave me any measurements at all that were not just noise.

Undeterred, I read the docs again and attempted to do a manual configuration of the app. Unfortunately, if you're lucky enough to find the information on the "custom" calibration for the app, the docs are obtuse and don't really explain what the settings in question really do.

As a last resort, I contacted the author through the contact link on their website (which contains almost no information about the app itself). It's been two weeks now with no response whatsoever.

I'm sure this sort of technology for the iPhone will improve over time, but at the moment neither the app or the company are ready for prime time.
