How hard is it to manipulate data sent from an iphone. i want to use the iphone as a stepcounter and extract a bpm from a someone steps.

There are plenty of great applications around for getting accelerometer data out of smartphones. TouchOSC is probably a good place to start. You may also need the CNMAT tools for working with OSC if you haven't got them already.

As a guess, you could probably track steps by looking at peak accelerometer numbers. I'd imagine there is a jump each time the foot hits the ground.

Hey guys :)

I'm kinda new to max and therefor have a lot of questions. I also wanna get the stepcounting data from my old Iphone 3GS into max to manipulate the speed of music. I guess I need MIDI-data for that?
I got touchosc (besides some basic functions with logic pro I couldn't get any usefull functioning going on) but no idea how to get any data out of it...

I'dbe very glad to get some help with this!
