App developed in Android Studio used to track the lifepoints of the players in a Duel. The first app I developed, it uses a viewpager to hold the information of all the players and it's displayed one at a time. It focuses mainly in the design using the xml files and values to adjust according to the screen dimension and the language of the device. It also stores the information of the user by saving his preferences in the settings menu, this includes the Names and the position of the player they have assigned.
