Hi All, I've spent two days on this. In this case, I purchased Star Walk for Ipad and my connection was too slow for a download. I got a message saying download it to your computer and transfer to ipad. Is there a wifi way to get an app on the ipad desktop. I can transfer the file through Avatron Air Sharing or Readdle Docs. After that I am stuck. Do I have to use iTunes? Thanks so much. Happy New Years.
