Chess Clock: FIDE Timer

The chess clock built for real play.

Whether you're grinding one-minute bullet online prep, running a tournament arbiter's floor, or teaching a kid how to press their first clock — Chess Clock has the time control you need, and gets out of your way while you use it.

••••••••••••

EVERY TIME CONTROL THAT MATTERS
• Bullet: 1 min, 2 min
• Blitz: 3+0, 3+2, 5+0, 5+3
• Rapid: 10, 15+10, 25+10
• Classical: 30, 60, 90+30
• FIDE Classical: 40 moves in 90 minutes + 30 in 30 minutes + SD in 15 minutes + 30-second increment from move 1 — the World Championship spec, implemented exactly
• Armageddon
• Hourglass mode
• Go and Shogi: byo-yomi periods with FIDE-correct consumption
• Scrabble presets
• 17 built-in presets across 7 categories

••••••••••••

TOURNAMENT-ACCURATE
Fischer increment, Bronstein delay, US/Simple delay, Japanese byo-yomi, Canadian overtime, hourglass, and multi-stage transitions — all FIDE-correct. Move-by-move state persists across every action, and you can undo the last press if you fat-fingered a tap.

••••••••••••

BUILT FOR THE TABLE
• Two big edge-to-edge tap zones — nothing to miss under match pressure
• Flat-on-table mode rotates the opponent's clock so both players read face-up
• Monospaced digits, tenths of a second in the last 20s
• Six visual skins: Classic B&W, Wood, DGT green LCD, Tournament navy & gold, Neon, Midnight — pick one per match
• Voice announcements at 60s / 30s / 20s / 10s / 5-4-3-2-1
• Live Activity keeps the clock on your Lock Screen and in the Dynamic Island

MOVE HISTORY & ANALYTICS
Every press is logged with its duration. When the match ends, review:
• The full move timeline with per-move deltas
• Per-side stats: moves, total time, average, longest think
• Cross-match analytics: your play streak, average move time, longest think ever, time-trouble rate, wins as White vs Black
• Export as PGN with clock annotations for Lichess, SCID, ChessBase
• Or export as CSV or JSON for your own analysis

••••••••••••

BROADCAST & SPECTATE
Tap share to generate a 6-digit code. Anyone with the code can watch your match live from iPhone, iPad, Mac, or the web at chessclock.app — clocks sync in real time. Two-code model: give the edit code to your opponent, the view code to spectators.

DESIGNED FOR SERIOUS PLAY
• iPhone, iPad, macOS, visionOS
• Landscape and portrait supported
• Native SwiftUI — buttery, low-latency
• No ads, no accounts, no distractions
