During the test, the palm of the hand must remain flat on the surface of the table (if you are using an iPhone) or flat on the surface of the iPad.

The test will automatically stop counting after the specified seconds as configured in the “Info” screen. For accuracy the test will be repeated 3 times.

To share the recorded results, click the export button in the bottom left-hand corner of the Results screen. The results will be attached to a new e-mail as a CSV (Comma Separated Value) file.

Bluetooth Keyboard

As an option, a paired external Bluetooth keyboard can used for tapping.

False positives

When a Bluetooth keyboard is used, the App will reject keypress data faster than 100ms. This is to minimize false positives originating from pressing 2 keys nearly simultaneously or from the autorepeat function when keeping a key down.  If such a condition is detected it will ignore the keypress and will display  ‘Tap —‘  on the screen.


The app has support to display a graph of the taps while a test is in progress to a compatible Airplay device, such as Apple TV. This could be used to provide visual feedback for the patient or research personnel during the test if required.
