Just playing around with the app I like the simplicity and how it tracks combat, hp.
My complaints would be that the monsters are only from the beastiary and there is no way to create your own. My group plays adventure paths and half the monsters in the ap are created for the ap. I would love to see the ability to add new monsters. So I could before a game add in the stats from monsters in the ap.
Also I would love the ability to add templates to existing monsters. This relates to aps as well as many of the monsters are slightly different such as an advanced shark, or a giant ...
Overall a great product, but may not see much use from my group.
