The K-D Balance App allows you to administer a K-D Balance test directly on the iPhone or iPod and sync with your BOS (Balance Online System) account. For optimal performance, it is recommended to use the same calibrated device for testing. If you have not calibrated your device see Calibrating K-D Balance(iOS)
