App Description
The audio ruler is a new way of measuring distances. Unusually to other apps, the measurement process is based on the sound. Specifically, the distance traveled by a sound way from point A (phone speaker) to point B (earphones). The app is based on a genuine technical paper and the algorithm behind it is fueled by advanced math.
