iPhone
New for iPhone Duo: half-fold it and Boardside becomes a real tabletop chess clock. Timers stand up, tap pads lie flat. Clear and fair on every iPhone, too.
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.
PRIVATE BY DESIGN
