Most poker clocks want an account, a subscription, or a laptop at the table. This one runs in your browser with no sign-up, works offline, and is ready in about a minute. Enter players and how long you want to play, and it builds the blind structure for you. [Rebuys, breaks, and payouts included.] Pro is $19.99 once, not monthly. It lets you run the game from your phone while the clock shows on the TV.
