The app is primarily for chess players, but not only for them. It can be used in the traditional simple way or with several types of time delays. Official and exact tournament rules, or for board games in specific game modes. It also has an hourglass and many other time modes, the possibilities are not limited to chess, you can use it for Go, Scrabble, Shogi and any board or skill game. Provides players with extremely accurate and precise time measurement thanks to special built-in algorithms and freely adjustable touch sensitivity. Useful settings make it easy to customise the game mode, and almost everything you need is there. It can be used in two layouts, the counter can be placed anywhere on the screen, the player can rotate its view and change its colour freely. The clicks and other events have very nice effects and sounds that you can also adjust so that they don't disturb you accidentally. Game modes: Basic chess - Standard chess clock with the usual operation, the clock timer counts down to zero. US delay - Simple delay, after each step the lap time is reset. If the lap time is exceeded, it is reduced from the main time. Bronstein delay - If a player expends more than the specified delay then the entire delay is added to the player's clock, but if a player moves faster than the delay, only the exact amount of time expended by the player is added. Fischer bonus - A specified amount of time is added to the players main time each move, unless the player's main time ran out before they completed their move. Forward counting - Time runs incrementally from the initial value until the set limit is reached. Also known as a reverse chess clock. Unlimited - Time passes incrementally from the initial value, but there is no limitation, the game can go on for as long as you like. Free to touch - The clock counts for the player who has just pressed it. Opposite logic to the chess clock and no time limit. Round based - When the round time runs out, the other player is next. Time limit is fixed for each round. Hourglass - All time spent goes to the opposite player. When the time runs out, the game is over. The app is completely free, ad-free and does not collect any data about you.
