If you want to play the party game Werewolf
(also known as Mafia), but all you are missing is a set of cards and you don't feel like using pen and paper, this app is for you. Simply configure how many players are participating, which roles you would like to use (e.g. how many werewolves etc.) and off you go. You will then be able to hand around your device and each player can tap to see their role.
The app is open source! Check it out at https://github.com/FauDroids/Werewolf
