Hi Darren
Sure. Go to the Profile's detail screen by A) Tapping the Profile "i" button inside a roast, or B) Navigating from Roasters > Your Roaster > Profiles > Profile.
From the profile details screen, tap the sharing button in the bottom right of the toolbar, and choose "Roastmaster Exchange". You can AirDrop this directly to another iPad (or use iCloud drive, Dropbox, email and such). On the receiving iPad, accept the incoming AirDrop, and choose a Roaster to assign it to. Finally, choose "Import as Profile" and it will now be on both devices.
Let me know if you have any problems.
