CYPD vs Tremor Analysis
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
CYPD
This app helps Parkinson's patients manage their condition by tracking medication intake and analyzing tremor data from an Apple Watch. It visualizes tremor patterns, includes motion tests and diagnostic questionnaires, and generates reports for doctors.
- Medication intake tracking
- Apple Watch tremor data analysis
- Tremor visualization graphs
- Motion tests
- Diagnostic questionnaires
- Medication schedule management
- Doctor report generation

CYPD app is intended for individual use by patients who suffer from trembling hyperkinesis (tremor) in Parkinson's disease. It keeps records of the intake of prescribed drugs, to increase treatment effectiveness by providing the doctor with accurate information about the patient’s tremor obtained from Apple Watch, as well as on the effects of anti-tremor medication the patient is currently on. The data obtained from Apple Watch is stored in the patient's smartphone and can be visualized. The information can be transferred to the doctor as reports according to any established form. CYPD app functional: - collecting information about patient`s health; - analysis of the data collected from Apple Watch; - displaying the patient's tremor as a graph; - motion tests; - diagnostic questionnaires for PD; - prescribed medications schedule management; - generating and sending tremor medication influence reports to the doctor. - provide your doctor with information about your health, stored in Apple HealthKit.
Tremor Analysis
This app quantifies hand tremor frequency using accelerometer data. It performs a Fast Fourier Transform to display component frequencies and magnitudes, allowing for customization of data collection and analysis. Results can be viewed on an Apple Watch or synced to a main device.
- Accelerometer data collection
- Fast Fourier Transform (FFT) analysis
- Frequency and magnitude charting
- Customizable data points and axes
- Apple Watch integration
- Data syncing between devices

**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.
