**App Overview**
This app uses your smartphone's camera to measure lap times for Mini 4WD cars, RC cars, Kyosho Mini-Z, and similar vehicles.
It offers detailed settings to ensure accurate measurements.
By entering the course length, speed can also be displayed.


**Main Features**
**- Font Size**: Adjust the font size for lap times and statistics. Choose the optimal size for visibility and layout.

**- Decimal Places**: Specify up to 9 decimal places for speed and time values. Choose between high precision or simplified display.

**- Screen Rotation**: Configure the display for easy viewing in both portrait and landscape orientations.

**- Sound Effects**: Enable sounds for lap detection and start events. Useful for notifications or silent operation depending on your needs.

**- Light**: Turns on the LED light during camera use to improve detection accuracy in dark environments.

**- Detection, Measurement, and Camera Settings**: Fine-tune camera FPS, detection sensitivity, focus, and zoom. Customize detection conditions based on your environment and course.

**- Detection Point Settings**: Specify which points on the screen trigger lap detection. Choose freely from 81 selectable detection points.

**- Course Length Settings**: Automatically calculate accurate lap distances based on course type (2-lane/3-lane) and selected parts. Used to compute lap speed.

**- Manual Measurement**: You can measure manually when the camera is unavailable or permission is not granted.

**How to Use**
1. Place your smartphone on the course (ensure it is stable and vibration-free).
2. Tap Start.
3. When the car passes, measurement begins.
4. Tap Stop after the desired number of laps.
5. Review lap and split times.
6. Share lap time data from the menu.

**Q&A**
**Q. Menu operations are slow to respond. **
A. When the camera is active, overall responsiveness may decrease. You can tap the camera image to stop the camera. Tap it again to restart the camera.

**Q. The Mini 4WD doesn't trigger detection when passing.**
A. If detection fails, try lowering the sensitivity value to improve responsiveness. The default is 100, but around 80 may work better. Detection may be difficult if the car and course colors are similar.

**Q. Speed is not displayed.**
A. Speed information will not appear unless the course length is set. Please enter the course length from the menu.

**Q. I set the course length, but where is the speed shown?**
A. Scroll the lap list to the left to reveal the speed on the right side.

**Q. Can I set a lap count for automatic stop?**
A. Yes. You can specify the auto-stop lap count from the settings menu. The default is infinite.

**Q. Does lap time accuracy vary by device?**
A. Yes. Accuracy depends on your device's camera frame rate.

**Q. Can I mute the sound?**
A. Yes. You can disable sound from the options menu.

**Caution**
Lap time accuracy depends on your smartphone's camera performance.
At 240 FPS, there may be an error of 0.0042 seconds.
