This is an army list creator, much in the vein of the old "Army Builder" that some of us used many years ago.

Haven't tried printing yet (mine's on the blink) but it has the advantage over Army Builder in that you can link the desktop app up with your phone, as long as you have a Dropbox account (and if you haven't, it's free, and if you get me to send you a referral I get added space).
Linking the two can be a faff, but someone sent me the link to a "how to" that worked: https://www.reddit.com/r/BattleScribe/c ... _tutorial/
I'm only using it for Kill Team and Frostgrave, although I downloaded the data files for Blood Bowl as well, but most of the popular games are there.
