Do you occasionally have wobbly knees and shaky hands but are not the least bit excited? Find now out if your shaking is still within a normal range with the iPhone-App TremorCheck.

• Reliable and correct measure of the strength and frequency
• Save and follow-up measured data
• Graphically display single results and trends


TremorCheck applies a clinically and scientifically proven method to measure and analyze human shaking, the so-called tremor. Measurements are made with the iPhone which has a very sensible 3-dimensional sensor measuring acceleration, recording the values of all three directions in space.

From ‘Shaky Sheldon’ to Shooting Star!
TremorCheck will make you a scientist! Record your data comfortably and analyze your progress. The results are displayed in easy-to-understand graphics. Retrieve single measurements as well as trends over time

TremorCheck calculates a number of values from the measured data:

• Dominant frequencies in Hertz: Number of vibration of the hands per second
• Performance / strength in mWatt: The strength of the shaking
• Amplitude: The maximum deviation of the tremor
• Synchronization: "Steepness" of the peak of dominant frequency

NOTE FOR IPAD USERS: TremorCheck works correctly in your iPad. Due to its size though, the device is not suitable for recording hand tremor.
