A free app for Android, by Veit apps.
In Dungeons and Dragons, a player’s actions are divided into three main categories: attacking, defensive, and utility. At the end of each round, the player is awarded points for each action, based on the type of action and the ability scores of the players and monsters involved. These points are used to determine who wins the round.
You can use the app to manage all the information about your character: your stats, like strength, agility, intelligence, and knowledge, as well as the rules for your campaign. It can be used as an initiative tracker or a skill challenge, for example.
