WheelCheck - Analyse your Tires app for iPhone and iPad

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.
