If anyone know about an accelerometer app that would play some sound when a certain threshold is reached.
or play a beep that increases in freqency, from one threshold to another, like, one beep a second, up to 4 beeps a second, when reaching some acceleration level, quiet below the threshold level.

The obejective would be to train for a better car driving habit.
All apps on the market have visual indicators for acceleration, but none have an audio monitor.

Note:
The phone is not necessarly flat in the car, so, some calibration would be required, when stopped, then when driving forward to detect the FORWARD vectorial displacement, being a combinaison of all 3 axis.

That should not be too hard to do?

Hello,
Such app doesn't exist but it might be soon. I and a few others are creating an app for a contest and we might use this idea.

there is an app called G-Meter by Toseeg - have a look, it might work for you. The sound alarm is for lateral g in there though, but it depends on the position of the phone, so it is possible to make it work for your requirements.
