It'd be great to have a NAV-only iPhone version for those of us whose cockpits are too tight to mount an iPad. The route would be planned on iPad / PC / Web and then synced to the iPhone app via the cloud.

Well, I have happily been navigating IFR all over Europe on a mobile phone for years - an HTC HD2 - which has been completely reliable; the £6,000 Garmin 430 is relegated to driving the autopilot. Trouble is, with WM6.5 now obsolete, if the HD2 goes on the blink I cannot buy another, and I really like the capacitive screen and the datalink via the phone, neither of which is available on the Demon device. So without dissing the iPad, which as I agree is great, I think it would be worth the effort of porting the programme, because there's going to be a vast variety of hardware options running Android. I for one can't find the space for an iPad in my cockpit, and the iPhone is too small, in my view.

It actually would be very nice to have a lite version, or nav-only version available on iPhone and Android. It doesn't make sense to try and plan a route on these small devices, but it would be nice to be able to load the route in it and have it available during the flight (maybe as a backup to another system?).

The 'other' software guys just released something like that. Not saying you show follow every move they make, but since i also use there software i now have a backup for my portable Garmin 495. But i prefer Skydemon, so...
