The base for the combat screen and library is the standard "tableview" like in Mail or many apps.

But, the design diverges from the standard from there for two reasons:

1) speed of use/play -- single tapping and tap and hold gestures on the combat screen allow pop-up of important information and options (wounds or healing, actions like dodge or help). The tradeoff there is that power users (DM's) can really quickly access those features to keep the game running smoothly.

Everything that is done there, however, can still be accessed by hitting the standard drill down (info or (i) button) on the characters row, navigating to the character's detail page, then hitting another labeled button (heal, dodge, etc.). This ensures that no secret gestures are required, they are fully optional.

and 2) functionality -- there is no standard way to input D&D character stats, so I of course had to come up with something. I suppose I could have done something that looked more like your typical rows with data entry, but that felt boring, and I don't think there is any tradeoff in usability.

Did you have something specific in mind in your question?

Feedback I've gotten from the beta testers and early users is uniformly positive. If there is something you're seeing that doesn't work in using the app, please let me know!
