**DISCLAIMER** Tremor Analysis does NOT provide medical advice. All medical decisions should be made by a doctor. Consult with your doctor or healthcare provider before making any medical decisions. This app is solely meant to assist with quantifying the frequency of a hand tremor. Please confirm all results with your doctor or healthcare provider using certified equipment. ** ** Tremor Analysis uses accelerometer data to calculate the frequency of a hand tremor. Simply press the start button to start collecting accelerometer data. Once enough data points have been collected, Tremor Analysis automatically performs a Fast Fourier Transform (FFT) which outputs the component frequencies and magnitudes. After performing the FFT, Tremor Analysis displays a chart of magnitudes vs frequencies from 1hz to 20hz. Hold or drag along the chart for more information about the frequency and magnitude on the chart. Customize the app by choosing the number of data points you would like to collect, which axis to collect accelerometer data from, and whether you would like to see rounded or precise data. Use an Apple Watch to record data from an alternative source. Analyze the results on your Apple Watch or send the results to your main device to be analyzed later. You can also sync the settings between both devices for easy configuration.
