Test your reaction time against the drag racing lights (Christmas tree lights).
Use the accelerometer to start, calibrate it, use a 5 second delay, and combine with location to have a simulated drag strip! Keep in mind GPS updates at 1hz so this is just for fun, not an accurate timing device.
Use as a simple start light when racing RC cars or slot racing (starts with a delay allowing us to set up our controllers).
Includes the option to set a vehicle reaction time, allowing a start on 3rd amber instead of reacting to green.
Select one of the following start modes:
- Stoplight - Green light comes on at a random time. Does not use vehicle reaction time.
- Sportsman tree - ambers light up sequentially 0.5 seconds apart, followed by the green light
- Pro tree - all ambers light up at the same time, followed by the green light after 0.4 seconds
1.7: - effect for new personal best or perfect start - simplify timer precision handling - add share screenshot feature 1.6: - UI alignment bugfix - credits ads and IAP 1.5: - option for manual staging (tap to stage) - option for haptic feedback (vibrate on light changes) - accelerometer calibration - drag strip with GPS: after start, a drag strip is measured using your device's GPS. Combine with accelerometer, manual staging, and a 5 sec delay to time your runs! (gps is 1hz so just for fun)
