To get started, you'll need a newer Apple iPhone or iPad. It requires having the A12 processor chip which is available in the 2018 iPad Pro or newer (Any new iPad is sufficient) or the iPhone XS, 11,12,13 (or newer).
To get going, first, open the OnForm settings and enable support for BodiTrak. From the home screen tap the "gear" icon:
Next, connect your iPad/iPhone to the BodiTrak's wifi, usually a "BT2-***" name:
Now simply open the camera from any library, and you'll see the BodiTrak window appear, record video as you normally would and you're done! Yes, it really is that easy.
Once you've connected it's just a matter of stepping on the mat, hold still a few seconds for it to auto-center, then swing away!
