What's New
Updated for new iOS versions.
App Description
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).
