What is the data size of the WingX Pro 7 installation files and databases including the app itself and the VFR Sectional, IFR Low Enroute, IFR High Enroute, and the full "All Charts(IFR)" databases?

I've noticed that the databases for different aviation apps have different sizes. What is the total storage for WingX Pro7 if you select the option to download all of the following databases:

  1. List item
  2. VFR Sections
  3. IFR Low Enroute
  4. IFR High Enroute
  5. All Charts (IFR) - USA

My understanding is that WingX Pro7 uses higher compression than foreflight, leading to smaller database sizes, but I have been unable to find this information on their website, nor have their customer service responded to my email question.

UPDATE: I got my hands on a 16GB iPad Air and installed the latest version (July 2017) of WingX Pro 7 and downloaded all of the databases for the US including VFR and all IFR charts and plates for the Contiguous USA, plus terrain information. The only database I excluded was the High altitude IFR enroute charts. The total storage used by WingX Pro7 on the iPad is reported as 4.62GB.

2nd UPDATE: I finally got a response from HiltonSoftware on this question. They responded as follows:

    $\begingroup$ The most you can get... Data sets are getting bigger all the time. Also depends how much distance you want to traverse, the father you go in one shot the more you need on hand. $\endgroup$

    $\begingroup$ We usually avoid questions like this because the answers can change so quickly. I'd contact Hilton directly to ask, they'll know how much space is required for various features and which hardware is compatible. $\endgroup$

    $\begingroup$ Example: When I bought my iPad 2 years ago when I started flying I got the 16GB mini. It was more than enough at the time. Now that I fly farther and Foreflight has started to include more data like their new maps, and more airport info than they once did I push the limits of storage just keeping all the charts I need for the northeast. i.e. get the most you can now and it will last you for a while, eventually you will need to upgrade. $\endgroup$

    $\begingroup$ @JScarry that is interesting. Do you know when FAA changed to vector form? My comment about Hilton using more compression was based on article I read online dated 2014, so its very likely it has changed since then. If you can track down some source to confirm current WingX total database size, please answer question and collect the bounty! :) $\endgroup$

    $\begingroup$ @Devil07 It turns out that they are not exactly vector files but GeoTiff format. Previously they were scans of the paper version and now they are completely digital. I don’t recall exactly but it was not more than 2 years ago. The neat thing is that you can zoom in really far the text is still readable. $\endgroup$

The app itself only takes up about 15-20MB, according to the Google Play or iTunes app store, where as ForeFlight takes up 226MB (almost a quarter of a gigabyte) and Avare is less than 2MB and free. After downloading a good handful of charts, Avare is about 250MB. If you are very tight on space and running Android, you could try Avare. Otherwise if you need WingX Pro 7 or are on Apple, 5-6GB is what you should have free if you plan to use all the charts. If you're buying a new tablet, try to go for a 32GB model to be safe and have plenty of room for other apps additionally, otherwise 16GB should also work.
