take a look at the FREE version 2 :)

AccSpeed 2 : https://play.google.com/store/apps/details?id=com.Celltop.AccSpeed2

AccSpeed is the FIRST digital speedometer offering the possibility of combining the GPS speed measurement with those given by complex calculations on the phone accelerometers.
The posted speed can be expressed in MPH or km/h, and the app also provides access to measurements which are:

- The maximum speed
- Average speed
- Altitude
- The covered distance

You might have noticed how multiple applications regarding speedometers are slow and unresponsive.

Well it's simply because they only use the GPS speed measurement, which only updates every second.

With AccSpeed, a button allows you to combine the speed given by the accelerometers with the GPS speed.

"Yes it's good, but what does it bring?"
Well when you are driving and you accelerate, AccSpeed measures this acceleration, and calculates the speed of movement every 0.01 seconds (we are far from the one second of the GPS ;) ).
So the speed displayed on the phone screen is extremely responsive, the smallest pressure on the accelerator or brake pedal will change the speed almost instantly.

To summarize:
-The speed measurement by GPS provides precision.
-The speed measurement by accelerometers brings reactivity.


USER MANUAL :

For correct use of the "use the accelerometers" option of AccSpeed, kindly read the rules of use below.
(None of these rules apply if the option is disabled)

1. The phone must be kept fixed in the vehicle, and therefore can not be held in the hands.

2. The phone screen should be placed perpendicular to the road, with the ability to incline forward or back.

3. Inclining the phone will change the value of the posted speed, so you have to wait a few seconds before the auto-calibration is performed.


Note:

Accelerometers present in the phones are very blunt instruments, and their measurement qualities vary from one phone to another. It is therefore not impossible that the speed measurement is slightly wrong, but this should not prevent correct use of AccSpeed.
