WheelCheck - Analyse your Tires

WheelCheck provides an easy way to test the wheels of your car for unbalances. It measures vibrations and visualizes them intuitively.
It creates a diagram, where users can look for lines and get the strength of the unbalance from the intensity of the lines.
WheelCheck contains high sophisticated mathematical algorithms.
To fully pass a complete measurement cycle, the car needs to be driven the whole speed range (e.g. 0 to 150 km/h). Hence, the measurement takes about five to 15 minutes.
The supported speed range is 0 to 260 km/h and auto scaling is supported.

How to use it:
1.
Start the app and start the measurement.

2.
Put your iPhone/iPad onto the dashboard or into the oddments tray. Avoid placing it on soft surfaces and never hold it in your hand, thus any vibration would be blocked.

3.
Plan a 15min drive to measure a range of 0...60mph (0...100km/h). Try to vary the speed often. The most left row shows the confidence for each velocity. Try to get a solid green for best results.

4.
And most important. Always watch the traffic. WheelCheck must never distract you from the traffic. Inputs are never needed during the drive.
