Field notes
The homepage separates automatic camera measurement from a video workflow that lets users step through frames between two points. It says the camera mode uses an object's size as a reference, but gives no accuracy figures and describes some results as approximate. GPS tracking and a coach-oriented mode are also presented; the Android app is described as coming soon.
