I need a bluetooth accelerometer, any such thing out there that comes with a program on either pc? if it has an app for ios/android that would be even better. 

 

This would be for a science project to measure g force / acceleration and would need it to be as small as possible. I know this is not a mass market product so I can't seem to find it online.

I think you are specifically looking for a device you can attach to another object to measure it's movement.

 

I don't think you will find said object lying around for sale in the whole of Thailand, but if you do a google search for Bluetooth accelerometer you might find some nearby websites that sell such things. Especially if you did a search against an Arduino Forum.
