INTUITIVE CLOCK DESIGN

Player 2's display is rotated 180 degrees so both players face the screen. The active player is always clear through background color changes and text color coordination. A pulsing "Tap to start" or "Tap to resume" indicator guides gameplay. When time runs low, the display flashes red. At game end, the winner shows in green and the timed-out player in gray.

Move counters, byoyomi period indicators, and Canadian overtime move trackers are displayed directly on the clock face when relevant.

HANDICAP MODE

Set different time controls for each player. Any combination of presets or custom settings can be assigned independently to White and Black.

5 COLOR SCHEMES

Choose from Obsidian, Emerald, Sapphire, Amethyst, or Mahogany. Each scheme provides distinct active/inactive player colors in both light and dark modes.

SOUND AND HAPTIC FEEDBACK

Audio tap sounds on each move, with configurable low-time alerts. Choose your warning threshold: 10, 20, 30, or 60 seconds. Haptic feedback provides tactile confirmation on every move.

GAME ANALYTICS

Every completed game is recorded with full move history. Review total games played, average duration, and average moves per game. Tap into any game to see per-player stats including fastest move, slowest move, average move time, and a visual bar chart of move durations.
