I downloaded it a couple of weeks ago and at first failed to see the point of it. But recently i realised it took me to input all the values from the codex (which is rather tedious) but when its done is actually incredibly useful. You input your army and its values from the codex and you can create lists with or without the extras you have in seconds. At the minute im steadily going through the Space Marine codex and entering all of the units and characters onto Quartermaster, so if anyone gets it and would like a full SM template to build their own specific lists PM me and i'll be more than happy to share. It really beats writing out lists on paper from the book, but i must admit i felt like a bit of a wally slapping an iPad down on the table last time i went to play at Games Workshop. So i transfered Quartermaster to my iPhone and sent myself the template i had built and it worked a dream. So for all you Apple users out there this comes recommended from me. It would also be good to hear from any other users of the app to see what they thought? Also if anyone is up for sharing templates i would be a willing recipient.
Thanks,
