Works for me
Interesting 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.
Interesting, but couldn’t get it to work
Bought it just out of curiosity, and it looks like it’s doing something. There are a lot of adjustments you can do, and I didn’t spend too much time trying to figure it out. It seems to lock in at the same distances regardless of where it’s used. I’m wondering if my older phone (iPhone 6) just doesn’t have what it takes.

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!
Crash within 3 seconds
Tried uninstalling and reinstalling on my iPhone 6 several times but the program exits after 3 seconds every time. Would have been interested to "experiment".

Doesn't work in iOS 9

broken
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.

Broken!
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?
Nope
Doesn't work on my 6. Shame. Looks to be a cool idea.
