Mini4WD-LapTimer 1.0.9

It is a timer application designed to measure lap time, fastest time, and average time of Mini 4WD with the camera. Manual measurement is also supported.

• How to use
• From the settings menu, users can customize settings such as passing sound, vibration, number of lanes, number of laps, course length, detection sensitivity, and unit measurement.
• Select the desired number of lanes; one lane can be selected if unsure.
• Specify the number of laps for automatic measurement completion.
• Set the course length for speed calculation purposes; not setting it won't affect measurement accuracy.
• Ensure the device is positioned to match the selected lane and course, with slight deviation being permissible within Mini 4WD passable limits.
• Tap the screen and await the Mini 4WD's pass before starting the run.
• Commence the Mini 4WD run with measurement ceasing after the pre-set number of laps. Records can be viewed by tapping the button in the bottom left corner, and shared via Twitter, memos, or email using the Share button.

• * Long press to stop measurements and return to the top screen.
• * Manual measurement is available via the button at the bottom right for simple measurements outside the course.
• * Detection Method: Pass judgment occurs when the camera frame pixel's average brightness surpasses the set sensitivity. Sensitivity levels (85, 90, 60) determine brightness changes needed for detection. Accuracy improves with a fixed device; shaking won't impact readings unless significant brightness changes occur.
