Sonar Ruler for Positive User Reviews

Great toy if instructions are readLots of fun to mess around with..Version: 1.0

Very intriguing appThis 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..Version: 0

I love these thingsI always wanted one of these for the iPhone. You need to experiment with it and get used to how the results come back. Sometimes it's a bit tricky to figure out where on the spectrum the sound is coming back (most likely because other noise).Version: 0

Remove the case!I have an iPhone 3G, and I thought the app wasn't 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..Version: 0

Amazing! Works as advertised.I'm amazed at how great this appworks. You usually fall with in the .5 to 1 inch of the actual distance. For .99 cents it's worth the price. They need to come out with one that plots out the room for you. Echo location for the win!.Version: 0

Pretty Accurate, cool interfaceI measured my garage from like 15 feet away and checked it with a measuring tape, it was pretty close. I had to change the default temperature since I'm out in Phoenix and it's pretty hot..Version: 0

BrilliantWorks well.Version: 0

Works as advertisedThis app works as advertised. It has surprising accuracy at around +/- .5" or better. There are a lot of options, but it is surprisingly easy to use. Very little adjustment is needed for most measuring. The interface is good, but some components (sliders) could stand to be larger for easier manipulation. To get good measurements, all you have to do is place the orange dot at the peak of the wave, and locate the blue dots around the larger portions of the wave. Some adjustments are needed to measure thing that are very close (under 1 foot). The most difficult part is analyzing the results and throwing away the measurements that aren't correct. The correct one tends to stay steady, while the phantom results come and go. Overall, the app is quite an amazing utilization of the iphone hardware..Version: 0

Suprisingly accurateIPhone 3G- accurate as long as you keep it level and at a 90 degree angle to the surface you are measuring. If you have a first gen save your money. It will not work with the lower quality mic. Great app, thanks!.Version: 0

Really works!I'm not going to lie, at first I thought this wouldn't work very well, but with my testing this app was accurate to around 0.5 inches!! Amazing! Great job with the app!.Version: 0

Not perfect but worth the cost!I don't write a lot of reviews but I absolutely support this app and I think you should too. This app isn't 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..Version: 0

Impress your friendsWith how much cooler your iphone is than another smart phone. this seems to work because the mic and speaker are next to each other or thats what i understood from watching the intro video. i dont know any other of the smart phone that have this..Version: 0

Nice workI had this same idea a while ago, I figured someone would make it.Version: 0

Works Great on 3GsAmazing. I was not expecting this to work, but had little to lose because of the low price. It is accurate and works just as the description says. Make sure to watch the video for instructions..Version: 0

Very good!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 doesn't work well with 2G and it's in BETA..Version: 0

Its amazingIts amazing the app is incredible.Version: 0

Yes, it worksThis app really does work. Don't expect miracles, its accuracy level allows for "rough planning", not exact measurements. Being sound/echo based obviously there are limits, noisy, windy or open spaces (without a barrier to point at) are not going to be very successful. Watch the video to maximise its success, if you don't do some of the physical actions noted in it then you won't get a result. One limitation that I feel should be corrected, and is the reason for 4 not 5 stars is that it currently only works horizontally, vertical is pretty much a fail. I have no idea about the maths involved with using echo location to determine distance so maybe there is something really hard with vertical. Anyway, this is a fantastic and innovative use of a phone and no doubt benefits from the physical design of the iPhone (location of mic and speaker). I hope the developers continue to improve it (actually it just occurred that if either mic or speaker have been effected, maybe by water the results would be mushed). The only thing that I imagine would be more accurate is if a tools company make a dock connector accessory that does laser range finding..Version: 0

ReviewInteresting. Seems to work most of the time. More of a "impress the Boss" type of app.Version: 0

Decent, not too bad.I can get some fairly acurate results. Although if could use a face lift. User interface could be tweeked a bit. Some instructions could be made clearer. Took some fiddling about to understand it. That being said ,if you love an interesting toy and are a bit of a geek, worth a look..Version: 0

Accurate, awesome vintage looking science appAwesome. It's actually accurate! And it has a cool 90s vintage PC science software look to it. Whoever said it was "unfinished" is wrong..Version: 0

Great App!Wow, a sonar ruler that works as advertised! As long as you dont need accuracy down to like a tenth of an inch, its perfect. I use it for quick room measurements and the like, and it works like a champ. Great job!.Version: 0

Why are people moaning???I get results within a couple on cm's I'm not gonna use it for work but it's so clever..Version: 0

Buy It NowThis is a fun and truly innovative application. It works just fine. I used it to measure how much speaker wire I needed to cut from the spool, and for the first time didn't end up with an extra 3 feet of it around the speakers to trip on. However, you shouldn't rely on it if you're planning to build new kitchen cabinets. Well worth the single dollar..Version: 0

This is quite interestingIf you are into science and learning more about the world around you, I would recommend checking this out. The developer does a good job of explaining the principles inside the application. Cool!.Version: 0

VERY COOL APP!?!App works like it should, accurate, and easy to use. What more do you want!?! If you are skeptical (like I was), buy it, it really works!?!.Version: 0

WorksIt works as described but make sure you watch the video when the app starts. It tells you how to hold the phone and what you can measure etc.. So it works, but it would be cooler if it could measure people or small things also..Version: 0

Works fineFor the people who complain a few tips. 1. It works on sound. 2. Don't talk or have people talking while using it. 3. Don't 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 I'm sure the results will be better..Version: 0

FascinatingThis is not a real utility as background noise will interfere with measurement. However, it is a fascinating experimental tool and one of the more innovative apps out there..Version: 1.0

Awesome ConceptWhat 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!.Version: 0

Awesome!I bought this app simply on the cool factor (and I -never- buy apps). Great job! Docked a star because the custom settings change the estimated distance over way too high of a range. If docs were included to explain the calculations so that accuracy could be increased this would be a 5 star..Version: 0

Kris cookSuperb idea. You get good results if you use it properly. It's never going to be a tape measure but it's pretty good for estimations and for looking cool..Version: 0

Works surprisingly wellEven if it isn't very useful, it is really cool..Version: 0

AmazingWow so sick.Version: 0

Wow!Amazing! You'll actualy see the distance change as you move closer, and further from the wall. Reminds me of what Bruce Wane's phone did in the last Batman movie! Only way to make it better, would be if you could map the room out, by standing in the center and turning in a circle. .Version: 0

Very goodVery accurate if you know how to work it.Version: 0

Works for meInteresting app. shows principles of sound ranging. Ok in metric and imperial. Ok, it’s a bit quirky and there are lots of ghost echoes at distances other than the “real” one but overall it works for me. Needs better information on what is on the screen and the tweaks that can be done..Version: 1.21

Very accurateDown to the decimal accuracy. Just point it at a wall and get the distance. Once it is calibrated right it is very accurate!.Version: 1.21

Kewl but missing one thing ...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..Version: 0

IngeniousGood fun really clever use of the iPhone. Is there a real app opportunity here for blind people?.Version: 0

Have a Go With This one,,IT's like a bat or something... uses echoes, you can hear the clicks.. pretty coo.Version: 0

This ruler is very accurateTo 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..Version: 0

Execlent AppI've tested the accuracy of Sonar Ruler in several different setting and as long as you have watched the video you will achieve excellent results..Version: 0

Its like having a lab in handIts 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.Version: 0
