Duel Time app for iPhone and iPad

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 opponents 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!
