RallyMeter Calibrator for iOS

When participating in any form of classic car event, a key piece of information is distance travelled, which is then also used to calculate your speed in speed controlled events. To ensure the distance shown on your rallymeter corresponds to the distance measured by the event organisers, you must first calibrate your rallymeter.

The RallyMeter Calibrator allows you to enter the official measured mile distance, your measured mile recorded value, and current calibration value (where applicable), and gives you the correct calibration setting or adjustment for the event and your vehicle.

The app supports most popular brands of rallymeter including:

  • Halda Tripmaster
  • Halda Twinmaster
  • Halda Speedpilot
  • Brantz International
  • Brantz Retrotrip
  • Brantzmaster
  • Monit
  • Terratrip

For Halda Tripmaster and Twinmaster users, you can select the X and Z gears you have available, and the app will give you the selection of gears that provide the closest calibration setting.
