As you may know, I'm the developer of PackageReader (http://appstore.sdl.com/app/packagereader/145/
I am thinking of doing a mobile version of PackageReader, on Windows 10/Windows 10 Mobile and Android. I know you'll ask about iOS, but unfortunately Apple's proprietary hardware is required to develop for iOS and I simply don't have the financial resources to spend on Apple hardware right now.
The app would basically do the same thing as the desktop PackageReader - allow you to quick open a Studio Package on the go to check out files, word count etc. - though obviously no Open in Studio option ;)
Would such an app be useful?
