Lift Pulse serves as a journaling app to record motion data due to hand tremor.
At Lift Labs, we came up with a way to record a person's tremor using the phone's accelerometers. Using a Fourier Transform, this app can identify your tremor and calculate it's magnitude. You can set your baseline tremor (tremor on a normal day) by tapping the circle with your result. Subsequent readings will compare to this baseline, and the circle displaying your result will change color accordingly.
This app uses cutting-edge algorithms to detect and quantify motion. In its current form it is a useful research tool but not meant for disease diagnosis.
