My MTG playgroup kept taking too long to play rounds because of indecision on which cards to play, and we consistently ran out of time part-way through games.
A proven solution to this problem already existed - chess clocks. However, those only work for two-player games, and we play games with the number of players ranging from 2 to 6.
So I made a little web app that's like a chess clock but supports several players rather than just 2. It's designed to be used on a phone and put between the players on the table. Your turn ends when you tap your clock. There's also a pause button for during combat so that you can't unfairly run down another player's time while deciding which creatures to block with. The KO button distributes a defeated player's remaining time amongst the players who are still in the game.
