Boardside: Chess Clock

Half-fold your iPhone Duo and it becomes a real chess clock: the timers stand up facing the board, the tap pads lie flat under your fingers. On every other iPhone, Boardside is the clearest two-player clock you can put beside a board.

MADE FOR IPHONE DUO • Tabletop: half-fold the phone and the timers move to the upright half, like a tournament clock, while the tap pads and controls sit on the flat half. • Open it flat for the classic face-to-face clock, or keep it closed and play on the outer display. • Fold or unfold mid-game. The clock keeps running without missing a beat. • Swap sides so White’s clock is always on White’s side of the board.

EVERY TIME CONTROL • One-tap presets for bullet, blitz, rapid and classical: 1+0, 3+2, 5+3, 10+5, 15+10, 60+30 and more. • Custom controls up to three hours per player. • Fischer increment, simple delay, Bronstein delay or sudden death. • Your four most recent controls stay one tap away.

FAIR AND CLEAR • Huge, high-contrast digits, with tenths of a second when time runs short. • Only the player on move can stop their clock, so a stray tap never costs a turn. • Hold to start: both players hold their side for a shared three-second countdown. Or start with a single, confirmed tap. • Low-time warnings at 30 and 10 seconds, with optional sound and haptics. • Pause with confirmation, undo the last switch, and a clear flag-fall result with the final clocks. • Timekeeping that keeps counting correctly through notifications and app switches, and a screen that stays awake while you play. • VoiceOver announces the start, low time and the result.

YOUR STYLE • Modern or Tournament felt clock faces. • Light, dark or automatic appearance. • Player names and four colors per side.
