It doesn't work. Forget this app.
Purchased this app thinking it would simplify transfer of photos and files between devices. It does not support iPad to PC bluetooth connection nor can a connection between iPads be established. The app has been deleted from my iPad because it does not work. I am requesting a refund.
I expected an app that allowed the transfer of files between more than just iOS devices, specifically my Mac, but that was not possible with this app.
