PhotoGoniometer has been designed for limb angel measurements. Photogoniometer is unique since is allows the user, typically orthopedists and physiotherapists, to take a photo where the limb is extended and a second photo when the limb is flexed. The photos are superimposed, and limb position is indicated with three different markers, and the Range Of Motion (ROM) is calculated (figure 1, 2 and 3).

In PhotoGoniometer full version the user is able to save photos, both separate and merged including measurements. Date and comment can be added in saved images, and later shared or e-mailed and more (figure 4).
