Scoligauge

Part of the goniometer series developed by Ockendon.net, scoligauge uses the iPhone’s internal accelerometer to mimic a scoliometer.  The user first calibrates the device on a level surface, and then chooses to measure the angle based on the device’s position on an object or based on the camera image. The app shows a very realistic scoliometer model during the measurement.   Overall, the app relies on the accuracy of your iPhone’s internal accelerometer, but the app does what it says and allows for precise and objective measurements when a standard scoliometer is unavailable.
