Turn your iPhone into a sonar
Video: Sonar Ruler Demo
Curious that we bring this app. It’s called Sonar Ruler, costs 0.79 € and makes our iPhone in sonar, ie a distance measuring system.
It is an experimental application and works like sonar on a ship (for example): emits a sound that bounce off the wall or object and listen for the sound echo back.
As you can imagine the measurement is not exact, but the video of the header explains the best way to put the measure is quite appropriate to reality. It is a curious application of the many that populate the App Store.
