A Great Goniometer App

This is a fantastic, easy to use application to measure upper extremity range of motion. It has an easy to use interface and is far more accurate than a lot of competitor apps available. Highly recommended.

Excellent app for the right tasks

This is the first app I encountered which gives the accurate measurements of movements of shoulders and elbows at the tap of your iPhone. Essential tool for people who need to measure the joint movements.
