Caution : This app is for iPhone 4 & 4S.

This app allows you to measure accelerating performance of your car or bike.

Three different ranges of measurement can be set.

It automatically measures and shows results by the 1/100 seconds.

It is very useful to clarify the effects of your tunings.


[Basic usage]

-- Find a flat, straight course for measurement.

-- In the default setting, fix firmly your iPhone whose z axis is parallel to the direction of movement.

-- When you are ready to start, tap [Are you stopping ?] button.

-- Start any time you want ! (Screen shot #2)

-- When you start, it automatically starts measurements (#3)

-- When measurement of each range finishes, it rings a different sound, which can be turned off.

-- When measurements of all the three ranges finish, the display freezes (#1).


[Other functions]

-- Start and finish points of each range can be set by tapping them (#4).

-- The measurement axis can be set by tapping [Set Axis] button.
The -x, -y, or z axis can be selected (#5).

-- The nearest 6 measurements are displayed.

-- Average G force in the second range (dark cyan in the center) is displayed at the bottom.

-- You can quit measurement by braking lightly.


[Cautions]

-- Keep the law in public roads.

-- It should be basically operated by passengers.

-- Measurements exceeding 40 seconds are not recommended.

-- Automatic measurements may not work correctly in vibration-rich vehicles like single-cylinder bikes.
