Measure distances, up to 25 meters, with nothing more than your iPhone and Apple Watch!

This app works by measuring the time offset between the expected and actual reception of a sound signal, and then calculating the distance by multiplying by the speed of sound.

Many thanks to Anne Baumann for her support with the artwork.
