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:
"thats 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 youre 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

Pros and cons of Sonar Ruler app for iPhone and iPad

Sonar Ruler app good for

App works great to be in beta stage seriously anyone complaining about aesthitics and it not working need to read descriptions and reviews to see it doesnt work well with 2G and its in BETA.

I dont write a lot of reviews but I absolutely support this app and I think you should too. This app isnt perfect but what it is trying to achieve pushes the bounds of the technology for a scientific purpose. It also has amazing educational possibilities. The price is the lowest one can charge for an app and I truly believe money should go to fund a project like this. Kudos to the dev team. -Andrei Freeman 30 yr Apple 3rd party software developer.

I have an iPhone 3G, and I thought the app wasnt working. Well, I removed the phone from its leather case, and now it works GREAT! The software seems to be very sensitive to how the phone is being held and whether it is in any kind of protective cover or case.

This is really a well done app. The interface may not be the slickest, but it does exactly what it sets out to do. For those having trouble, consider a few things: 1)Sound reflects best off of hard flat surfaces, so trying to measure a distance to something absorptive or irregularly shaped may not work well. 2) Setting the air temperature will indeed affect your measurements. 3) Cupping your hand under the microphone and speaker as shown in the video will increase the volume of the clicks by focusing the sound from the phone; think of your hand as a crude megaphone or acoustic horn. This increases the signal to noise ratio and will increase the accuracy of the app. 4) Consider the ambient noise in the room. If you are trying to measure in a noisy environment, your signal to noise ratio will be poor and results will be inaccurate. In closing I really am impressed with this; I would not have thought that the built in mic had the sensitivity to detect reflections from those distances. Well done.

As you are adjusting for the temp, you need to set the calibration using a known distance. All in all this took a couple of minutes learn to use, but then it worked well. The video helps a lot.

For the people who complain a few tips. 1. It works on sound. 2. Dont talk or have people talking while using it. 3. Dont have your tv loud. 4. Keep your hands still while in use. I tried showing people at a party and it would not work. Music was blasting. So try to use it in a quiet place and Im sure the results will be better.

Some bad moments

The display is all marbled up and there is a squeeky sound coming out of the iphone4s instead of the clicking sound. Can you please fix that?

The app crashes immediately once it is started. Disappointing By when will it work? Im using a regular iPhone 6plus with up-to-Date operating system and no jailbreak or similar. If LaanLabs cannot make it work, they should be fair and proactively transfer the money back, otherwhise it is a case of fraud.

Hardly worth the 99 cents. More of a curio than an actual tool.

I tried to use it but it is not working for me. There is no instruction how to use, or calibrate.

Anyone saying this is accurate is either lying or a fool. Bounces all over the place even after taking the time to follow directions to a T. Needs development & Im not sure it will ever get to a stage where it can accurately b described as accurate

This Sonar Ruler application was very confusing and frustrating . What a waste of $0.99. I deleted this App. To bad the seller did not provide the video explaining how it works prior to having to buy it. If I had viewed the video first I would have declined buying this Sonar Ruler. I think the person explaining how to use the Sonar Ruler on the video seemed a bit confused as to how to use it.
