Duel Time is an app intended to be a useful companion when playing the Yu-Gi-Oh! Trading Card Game. Duel Time allows you to: - Keep track of your and your opponent's life points. - Calculate multiple operations at once. - Example: "8000 - 2300 - 400" - or more complex ones like: "8000 - (2300 - 1500) - 400". So you don’t need to do calculations anywhere else. - Support for portrait and landscape. - Tap with 2 fingers on your opponent’s life points to rotate them to see them more easily. - Undo calculation support. - A timer for tracking the time of a match - No ads! No Tracking!
