eyeTilt

eyeTilt is an easy, quick, and efficient app to determine how many degrees someone's head is tilted or turned. Before eyeTilt, physicians could use a goniometer or "eyeball" to estimate the degree of head turn. Now, you can use your iPhone or iPad to measure head tilt and head turn. 

To measure tilt: just hold up your device, line up the guide lines, and the device will tell you the tilt of the head. 

To measure turn: hold your phone flat, line the phone up with the visual target, then line up the phone with the head turn. Use for strabismus, torticollis, nystagmus, or any other way you would like.
