Sonar Utility uses sound to measure distance. But it is so much more than a ruler. It is the first iPhone app for generating 360° sonic images that show surfaces like walls, obstructions, openings (e.g., doorways), and other features. Use it to "see" in the dark. Sonar Utility is also a thermometer that estimates the ambient temperature using the physics of sound.
Note: For best results this app should be used in quiet environments. Works best with older iPhones (e.g., iPhone 4s).

I would suggest that you either take this app down or make it free. It does not seem to work at all.
It can't tell the difference between one foot or ten.
Does not work.
Should be considered for entertainment purposes only. Will not actually work, even after patiently following all instructions in a perfect environment.
With Family Sharing set up, up to six family members can use this app.
