Sonar Ruler vs Currency Converter

Sonar Ruler is a winner in the Best App Ever Awards - "Most innovative use of iPhone hardware" category! The Amazing New Sonar Ruler is an experimental app that uses echoes to measure distances with your iPhone! It uses the same principles that dolphins use to find food! It sends a short pulse from the speaker and measures how long that pulse takes to bounce off of something and return to the phone. It then estimates how far away you are. Use two devices to find the distance between them, without any wifi connection! Use "quiet" mode - with ultrasonic frequencies most people can't hear! Impress your friends with what this unique app can accomplish using only an iphone! GIZMODO.com: "that's a damned neat trick for a phone to be able to do." Features: - Set Units to feet, inches, or meters - Custom saved settings for measuring in different environments If you're a teacher, this app is a great way to teach students the principles of sonar, and how sound propagates through air. Enjoy! Follow us on twitter @LaanLabs NOTE: This is an experimental app, although it can be quite accurate, any measurements taken should be verified before using them.
