SpeeDX

SpeeDX is meant to be used when you do some upgrades to your ride and then want to see if it has any effect on car performance.

Requires no calibration, no adjustments and is not affected by the elevation or the movement of the phone.

It uses custom speed range, input your prefered start and end speed range, turn on time measuring and hit the gas pedal.

- Very accurate (Uses more battery life) !

- Please don't use it on public roads for your safety !
