Hi Anderson
You can export curves by tapping the action button in a curve details view and choosing export. You can send them to Dropbox or email them, and import on another device. Unfortunately, though, they are designed to be imported into a profile or a program. What you might want to do, is to create a profile called "Transfer" or something similar, then import them into that profile, then copy and paste them into the roast. It's an extra step, but it will at least give the desired outcome.
About the analyzer. Yes, you are correct - there's no space on iPhone. Plus I've seen lots of users who make really long curve names, so the space gets eaten up fast. I'll give it some though and see what might work. You're not the first to mention it, but lots of users have been pretty vocal about not liking clutter, so I try to keep things as open as possible. I've thought about making the label markers "draggable", so you could enter values by sliding those up or down, eliminating the need to select any curve at all - just drag the one you want.
In the mean time, instead of using the list, you can tap directly on the interior area of a curve to select it. Roastmaster will select the curve with the lowest level at the point you tap. If two curves occupy the same space, you can just tap twice without moving your finger to select "through" each one. The only variation is in the very beginning of a roast, when curves don't have enough screen area to tap yet, those get selected first. But the same general rule applies - just tap again in the same spot to select the next curve.
Hope this help, and thanks for the input!!
