(About mounting the iPhone)
- Mount the iPhone to the machine where the iPhone screen can be seen by the driver/rider. It can be mounted either vertically or horizontally.
- For 4-wheel machines, GPS reception is more stable under the windshield than under the roof.
- If you don't need to see the time while driving, you can put the app in stand-by mode and put the iPhone in your pocket.
(iPhone settings)
- Turn on Location Services.
- Allow LOCATION ACCESS to LapTimer.
- Turn on Precise Location.
(Remarks)
- Lap times are recorded together for each session. Approx. 10,000 laps are saved, and when the capacity is exceeded, the oldest lap times are deleted.
- When you tap the button, a dialog will appear to prevent the measurement from ending suddenly. Also, an option selection dialog may appear.
- If GPS reception is poor, operation may become unstable.
- It is not possible to measure in reverse direction.
- The developer assumes no responsibility for any accident, violation, loss or claims by third parties which may arise from the use of this app.

“Nürburgring Nordschleife (BTG)” measures lap times for the approximately 19.1 km BTG section used during public driving sessions.
BTG stands for “Bridge To Gantry,” referring to the section from the Bilstein Bridge to the Audi Gantry.
With this app, you can easily and accurately measure your BTG lap times. If you ever have the chance to drive the Nürburgring Nordschleife, be sure to give it a try!
