Audio Ruler - measure distances using soundwaves

It's a really cool tool that uses soundwaves to measure distances. It works by emitting a soundwave from your device and measuring the time it takes for the wave to bounce back. The app then calculates the distance based on that time measurement. It's a really innovative and useful tool that can be used in a variety of situations, from measuring room dimensions to checking the height of a ceiling. Definitely worth checking out if you're in need of a reliable and easy-to-use distance measuring tool!
