I downloaded Wingx Pro7 to my Ipad on June 30, which I believe is the first day it became available for download.
For this initial version, none of the weather charts (radar, satellite, etc.) could be downloaded without causing the app to immediately close. This was corrected by a software update a couple of weeks later and it now works fine.
Last weekend was the first opportunity to try it out on a local IFR practice flight. The following is only my own personal experience and opinions based on that flight:
1) The user interface is intuitive and easy to use. The application is fairly crisp in response to user input
2) I like it a lot better for pulling up approach plates than the ultracompact PC I had been using (running Pocket Plates software). It is faster, more responsive and the interface is a little easier. I like being able to see the desired chart within just a few seconds of turning the iPad on (no real boot-up process to wait for). Also, the annual subscription is less than Pocket Plates, and gets you everything that Pocket Plates provides, and a lot more (moving map, weather charts, etc.)
3) The moving map is pretty restrictive - the greatest zoom out possible is somewhere around 45 nm displayed on the screen
4) Arrival Procedures are displayed tilted 90 degrees - great if you are used to reading vertically, but not to easy for me when I'm flying. There is no way to rotate the view (if you rotate the ipad, the display rotates as well to stay same-side-up).
5) It is not possible to overlay radar maps on the moving map. While this is not useful in flight anyway (unless you have an in-flight internet connection), it would be helpful to see overlays on the planned flight path displayed on the moving map.
I have also spent a small amount of time comparing WingX to the trial version of Foreflight. One of the big advantages of Foreflight is that it includes Sectional charts and IFR charts in addition to the approach/arrival plates. However, its flight planning tool doesn't seem to be quite as quick with the brief testing I have done so far.
So far, I like WingX a lot. There are still some kinks to be worked out (like the 90 degree display thing), but it has great potential and the iPad seems like an excellent platform for the software.
Note: To use the moving map features when you don't have an internet connection, you need to have the latest version of the iPad, which includes a built-in GPS. Our iPad does not have any cell-based services - only WiFi at home. The iPad actually belongs to my wife, so testing is further limited by whether or not anything else is in the job-jar.
