How to I measure the vertical travel of my phone?

So I would like to make a app which when I strap it to my car I can see the vertical travel of my car to sort of measure it's suspension.

I believe this is possible in IOS although I am not sure how I would do it in Android.

I don't care about the side to side or the tilt of the phone just up and down.

Preferably the read out would be in centimeters.

Does anyone know where I should go to start researching this?

Thank you!

What you want to use is the phone's accelerometer. It won't give you position directly but you can calculate it. Computing position from acceleration uses fairly standard math formulas but there are some subtleties with real-world instruments.
