(About mounting the iPhone)
- Mount the iPhone to the machine where the iPhone screen can be seen by the driver/rider.
- 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.
(How to use)
1) Tap the "Settings" button at the bottom center of the screen to open the settings window. Select the circuit you want to measure. You can also select the speed unit and reset the best lap time in the settings window.
2) Tap the "Start" button at the bottom right of the screen to enter stand-by mode, the timer section at the top of the screen will display "Measurement will start when crossing the finish line", and the button will change to “Cancel/Stand-by". GPS is working when the speedometer on the screen changes to numbers.
3) When you enter the course, pass the final corner and pass the finish line at a speed of 15km/h / 9.3mph or more, the timer at the top of the screen will start running and measurement will start, and the "Cancel/Stand-by" button will change to the “Stop" button.
4) After that, the lap time will be updated every time you cross the finish line. The sector time is also updated each time.
5) When you finish running and tap the "Stop" button, the measurement will end and return to stand-by mode, and the button will change to "Cancel/Stand-by".
6) Tap the "Cancel/Stand-by" button to exit stand-by mode and the button will change to “Start".
7) Tap the "Results" button at the bottom left of the screen when the button at the bottom right of the screen is "Start" or "Cancel/Stand-by" to display all saved results. Best/2nd/3rd lap times and top speeds are also easily visible. You can select the part you need and copy or share it.
(About screen display)
1st line: Elapsed time. A message may appear before or after measurement.
2nd line: latest lap time
3rd line left: number of laps
3rd line center: Difference between the latest lap time and the best lap time before the latest lap. If the best lap time is updated, it will turn green with a negative value. If the lap time is later than the best lap time, it will be red with a positive value.
3rd line right: Speed
4th line: Best lap time. If the best lap time is updated, it will turn green.
5th line: Sector 1 time. The value on the right is the difference between the latest sector time and the best sector time before the latest lap. If the sector time has been updated, it will be green with a negative value. If it is later than the best sector time, it will be red with a positive value.
6th line: Sector 2 time
7th line: Sector 3 time
(8th line: Sector 4 time)
(About the measurement line)
- The finish line is the finish line of the circuit.
- Sectors rely on officially announced circuit information (or similar information). For circuits without sector information, 3 or 4 sectors will be used.
(Note)
- Lap times are recorded together for each session. Approx. 40,000 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.
