Sonar Ruler App Reviews

At times it can be within 5-10in but I dont event think with the new iph4 and its noise cancellation feature that it was developed right. My experience... When at 12in away it reads 26-36in. At 36in exactly its 40s to 50s

Need to update for iPhone 4 Retina.

Their are really only tow problems with this app one is that by its self the speaker on the iPhone isnt built to be. A sonar but if hook it up to a loader speaker like those $8 ones at wallgreens it seams to beater but the speaker and your mike obviously have to be facing the flat surface at the sam space I also hate the guess bar thing come on! But this was what I was looking for

Not much to say: it simply doesnt work. You can get an echo from time to time to register on the display, but anyway the reading isnt stable etc.. useless.

Does not sync with my iPod Touch 4G. It has a microphone... Please update!! I paid a buck and cant use it, partly my fault though. Update plz

I would not recommend this. It is difficult and not accurate.

Not work. Period.

Dont waste your time.

Lots of fun to mess around with.

Too many bells and whistles. Oh and it needs to work before anything!

This app worked great on my iPhone 3G, but doesnt seem to work with my iPhone 4. Sounds like signal is bleading from the microphone to the speaker, causing feedback and preventing it from working properly. Please update for iPhone 4+

Absolute waste of money. I have tried it in totally quite locations, keeping it level, and other things that should have improved results, but no luck. The closest to the correct measurement was within 2ft and that was in a noisy environment. Others say it worked on older versions of the iPhone. I could be doing something incorrect, but I have not found the correct procedure to make it work on iPhone 4S.

Used to work fine, now no chirping sound is emitted at all on an iPhone 5S. Help video URL is broken. Any one else gotten it to work recently?

Used to work great, but it no longer works on the newer iPhones running iOS 8.4. It runs and seems to be listening, but it no longer makes the chirps it needs to listen for. None of the adjustments seem to make a difference. I tried setting back to default values. Tried removing and reinstalling. Tried rebooting the iPhone.

Waste of time and money just shuts off immediately after opening app

Checked in on this once-cool app. Crashed the whole phone, forcing a hard restart.

after updating the system it does not work at all, it never worked well, but now it doesn’t work at all
