Just downloaded the app after visiting the booth at Sun-N-Fun. Im used it for some of my 900nm trip back home. Im completely aware that some of my information below might be due to not really understanding the app, but it is not very intuitive. The good-price. Sorry that is it. The not so good-downloading data. Very clunky data download/updates. Once starting the downloads could not stop the process to make changes. I realized that I selected the wrong states and had to delete the app to stop the download and start downloading the correct states. Original download took overnight and even then did not completely download all the Information. I thought I had downloaded all the chart types but later realized that the VFR charts did not download. Charts clarity. Loss of clarity to read airport /chart information-(especially in a cockpit environment) when Zooming into the VFR charts-not so bad with the low IFR charts. My guess is that This zoom clarity must be costly to develop and separates this app from the big guys. For information I have the IPAD 4. Geo-referenced approach plates. This is the main reason I considered this app. To say it plainly - they are not geo-referenced enough for me. Doing a few approaches I found that the referenced indicator was off by a few thousand feet -maybe a mile. I know that the referenced plates are only to be used as as a guide but other apps that provide spacial reference as part of their moving map functions (not geo-referenced) were as close as these geo-referenced plates. Summary. Great price and as good as most low cost small portable GPS units (Anywheremap ATC comes to mind) but not enough chart clarity when zooming using an IPAD. Very clunky download process that is so user UNFRIENDLY that there is a real possibility that you will not have the needed cached data when using this app off-line". This app has not convinced me that they are an alternative to the bug guys. As much as I dont want to spend the $$ needed for the big guys app, if I want the capabilities and features I have not found any lower cost options.
