Backgammon Clock

A backgammon clock and scorekeeper for two players sharing one phone between them. The app asks for no permissions at all. There is no network access, no analytics, no accounts, no ads, and nothing to configure before you can use it. The whole clock is a single HTML file inside the app. Features - Large area with the remaining total time/delay time for this move. Tap on your half to end your turn and start your opponent's clock. - Set the number of points to play for (1, 3, 5, 7, …, 29). - Set the reserve time per point (e.g. 2 minutes or 3 minutes), in 15-second increments. - Set the delay (free seconds every turn which don't carry over to the next turn), in 1 second increments. - Choose 1 of 5 colour schemes. - Turn sounds (for the turn change, when the delay runs out, and when the time runs out) on or off. - Pause/play the clocks. - Number of moves for this game and current score (when playing a multi-point match) are always shown. - Once a game is done, click the score icon in the middle to set the score. The clocks stay at their current time. - Adjust the clocks from the score sheet, if necessary. - Press the reset button twice (within 2 seconds, so you can't press it accidentally) to reset the clock and scores and start a new match. - Keeps running in the background, returns to the last known clock timings and scores after a crash or forced quit. - The screen stays awake while you play. Functional design is by Hans de Zwart, partially inspired by the open sourced Chess.com clock. Code is by Claude Opus.
