Okay, so here's my initial impressions:
1) On first launch, it said "installing" for a while before I got anything. But, I'm OK with that.
2) The data that comes with it from the store is expired (not too surprising) but they want you to register for an account. Cool - Except that it already had pre-filled an e-mail address for me that I haven't used in nearly 10 years! Scary!
Where'd they get that?
3) After putting in lots of account information (Voyager, DUAT, and an aircraft) the Downloads screen still didn't say that I could download anything until I switched to another screen and back. Also, the "Next" buttons and "Previous" button when doing data entry didn't appear to work.
4) Touch scrolling doesn't always appear to work for some reason, and when it does, it appears to be restricted to one axis at a time.
5) It fetches a DUAT weather briefing, apparently for a local flight, right off the bat. So, you can get an Area Forecast quicker than you can with ForeFlight (which requires you to enter a route and then ask it to grab a briefing before you get the FA).
6) For some reason, the "Recent" tab on the Weather page doesn't seem to work. I've tried both searching for airports on the Weather page, and tapping them from the Airports page, and nothing has shown up at all.
7) They put a LOT of info on a really long page, for the most part. So, rather than selecting what you want to look at, you have to scroll until you find it.
8) Getting a victor airway flight plan from KMSN to KCAD took about 15 seconds. Not too shabby. But boy, they need new icons for VOR's in the flight plan, they're pretty twisted.
9) Oh my... That flight plan is really off. They have it going MSN V228 OBK V84 JYBEE V215 HIC KCAD - That last leg ending outside the service volume of HIC. In addition, the distance MSN->MKG via the given route is 197nm, while the distance from MSN->MKG along V2 is only 146nm. Finally, there's NO way you'd ever get cleared on that route even if you asked for it, as OBK is smack in the middle of Chicago Approach's airspace - So I'm not sure why it didn't take the short route.
I hate to sound so critical - It is a decent app and I'll keep it, but it's also obviously a first effort for Seattle Avionics on iOS and could use quite a bit of refinement.
