Mount the phone securely before calibration, then do not move it.
Calibrate on a flat, straight stretch: hold still, then accelerate gently forward.
If you remount the phone at a new angle, tap Recalibrate.
GPS is used only to draw the on-device track path next to the gauge.
Always drive safely and follow local laws.
