"CarTest" is a tool app that measures acceleration performance of cars, motorcycles.
You can easily measure times such as 0-60 mph, 0-1/4 mile by CarTest.
It is useful for not only measuring full throttle performance but also knowing the usual acceleration on public road for safe driving.
Please use it with safety first. Please comply with the law when using it on public roads.

(How to use)
1. Fix the iPhone (or iPad with GPS) with CarTest installed on the dashboard of your car so that it does not sway. If your iPhone doesn't fall while accelerating, you can just put it on the dashboard or center console. When using it on a motorcycle, install it on the handlebar or fuel tank.
2. Tap the "Start" button (or "Start / Repeat" button). if the device isn’t capturing GPS signal, “GPS / in Prep" is displayed, and if the device is capturing GPS signal and the car is moving, "Waiting for Stop" is displayed. (If the device isn’t capturing GPS signal, "GPS" mark to the left of the CarTest logo shows in thin gray.)
3. When the car stops and the message “Start at your timing / Ready" Is displayed, start your car at your own timing. You will be notified by sound at the same time as the display. When your car starts, measurement starts and "Measurement Started" is displayed. The screen becomes a green image during measurement.
4. If your car decelerate during measurement, the measurement will finish and "Finished" will be displayed.
5. If the "Start/Repeat" button was tapped, when the speed drops near a stop, "Waiting for Stop" is displayed to prepare for the next measurement.

(Button function)
Stop: The measurement will end immediately.
Start: Makes the measurement only once.
Start/Repeat: Repeats the measurement. It is convenient for repeated measurement in urban areas where there are many signals.
share: A window opens to share the displayed result.
▲newer: After displaying the past result with ▼older button, tap this button to return to the newer results.
▼older: Displays past results from the stored history.
km/h / mph: Selects the unit of speed
↑ / ↓: Page scroll. These buttons are enable when there are other results behind while viewing history.

(Measurement range)
km/h: From 0-20 km/h to unlimited every 20 km/h. 0-400 m. 0-1 km.
mph: From 0-10 mph to unlimited every 10 mph. 0-1/4 mile. 0-1 km.

(Large speed display on the screen)
When in the stopped state (when neither the "Start" nor the "Start/Repeat" buttons are tapped), tap the "Stop" button twice to turn it on and off.

(Sensitivity setting of start sensing)
In the stopping state, tap buttons “Stop" → "▲newer" → "▼older" → "▲newer" → "▲newer" to open the setting window at the top of the screen. You can select 5 levels of sensitivity. Adjust if there are many false start sensing or if the response is slow. Probably no adjustment is necessary.
