New and new apps for iPhone are developed every day. These apps transform iPhone into advanced multifunctional gadget. The latest app from AppStore Sonar Ruler measures the distance with your iPhone. This app exploits the same principles that dolphins use to find food. Sonar Ruler sends the short sound pulse from the speaker and then measures how long it takes for sound to be reflected from a surface. It does not work precisely, therefore it is recommended to use the app for large objects which are in front of a phone.
Main features:
* Sonic distance measurement up to 60 feet
* Sets Units to feet, inches, or meters
* Custom saved settings measuring in different environment
* You can purchase Sonar Ruler from the App Store for $.99
