I just installed iFly on my iPhone and after an extensive 10 minutes of use, have a few minor comments.
It seems that iFly should/would use the compass integral in the iPhone for direction information, is that a capabiliity I missed, or is there a reason it doesn't exist?
Menu>Setup>Aircraft Profile. I triied to take a quick look at this feature, and discovered there doesn't seem to be a way, other than shutting the app down, to get out of the Profile page without setting up at least one aircraft. Similarly, it doesn't seem possible to delete the only aircraft profile once one is set up.
