All in one for your car:
- Head Up Display (HUD)
- Performance measuring tool
- g-Force indicator
supports km/h and mph
Create a chart of your speed, speedup, etc. and send it to you via e-mail.
Have fun !
If you want to start:
Hit the menu button and click "start measurement".
All readings won't start until the shown speed is below the lower value. So if you want to meter 0-50, you have to stop your car and wait til the phone displays 0.
The measurement starts automatically when you get going.
On the otherside the measurement stops only if your speed is 50 or more.
The GPS is slower than your car's speedometer, so you need to keep going until your phone displays 50 or more.
No worries, since carmeter does some calculation the end result should be right.
It's the same for all of the other readings.
Except for 30-50 mph, 50-80 mph, 80-120 km/h. There you need to drive slower than 30 mph, 50 mph or 80 km/h.
