Query about smartphone's accelerometer

[wackybrained]

Hi,

Is it possible to detect/measure car's acceleration or deceleration through a smartphone accelerometer ?

If yes, is it possible in all new smartphones ?
and how to implement it in android ?

Thanks

The Torque app can do this through a combination of phone and OBDII data (you need to buy a Bluetooth-OBDII adapter to use this app).
There is also ADyno, probably some others as well. Search the Play Store.

A simple search for "accelerometer" at the Play Store yields several options: https://play.google.com/store/search?q=accelerometer&c=apps
