My gaming group and I are looking at maybe augmenting our game with some apps. These are the ones I've seen so far that look interesting, but a lot of them do the same things...wondering if anyone has any experience with these and can offer impressions on which ones are best? DM apps: Tabletop Initiative Tracker DMTools RPG Buddy DMDJ Player apps: d20 Fight Club CombatDeck i4e Apps for both: Compendium Drums of War Power Cards 4E
