Gloomhaven Helper, an app that makes Gloomhaven faster to play, is being removed on May 22 by the developer because of a squabble with the creator of GH. I don’t care about the squabble, but want to preserve the app, which I purchased a while back.
I have an old iPad and an old iPhone and I’ll probably replace both within a year, and would like to have the app on my devices when I get them later. I have a Win10 laptop, though my wife has a Macbook.
Suggestions on how to preserve this now, and install it later? I have no clue how this would be done.
