A Goniometer is a device that measures angles or allows an object to rotate to a specific position. One of its most common uses is measuring a patient's range-of-motion (ROM) for a particular joint.
This measurement is used to determine the extent of a patient's joint injury and the expected speed of their recovery.
This goniometer is a basic app that is easy to use.

A strange flaw

When I touch start, it shows the beginning angle, then when I hit stop, it shows the ending angle. Do I have to add the numbers (or subtract) to get the total and turned. This shouldn't be necessary, unless I'm missing something. 'Start' should be set as zero, no matter the original angle, then rotating the phone would show the total and turned, regardless of original orientation. Did I miss something?

Invaluable tool after total knee replacement

I've never rated an app or anything online before but had to take a minute to tell you how invaluable your tool has been for me. I'm 48 and had a total knee replacement 6 weeks ago. I'm fortunate to have a top notch PT team at UCSF to guide me through rehab and, being a numbers person, wanted to buy a plastic goniometer like they use in PT to track my flexion & extension. On a whim, I searched for an app & found yours. Truly a fantastic way to motivate & push myself during home based PT. Has given me a great sense of accomplishment as I see the numbers creep up as the weeks pass. At 6 weeks post op today, I am at 115 degrees of flexion and pushing forward. I would HIGHLY recommend this app!! The PT staff had never heard of a goniometer app and have also been impressed with its accuracy and how easy it is to use. Thanks for making a great app!
