LapLync keeps every device on the same clock — precisely. Whether you're timing sprint drills on the sideline, running a swim meet, or coordinating a field exercise across multiple stations, LapLync starts all devices at exactly the same millisecond and keeps them together even when connectivity drops. FOR COACHES AND TRAINERS Hand athletes their phones, share a 6-digit room code (or let them scan your QR), and tap Start. The 3-2-1 countdown fires on every screen simultaneously. Laps and splits are logged automatically — no additional hardware, no manual data entry. FOR COMPETITION TIMEKEEPERS AND OFFICIALS Assign devices to each judge station or timing post, create a room, and every device runs in perfect sync whether they're on the same venue Wi-Fi or each using their own mobile data. Sub-50ms precision, anchored to Apple's NTP time servers. NEVER DROPS — THREE-LAYER RESILIENCE LapLync's connection system degrades gracefully so measurement never stops: • Bluetooth + Wi-Fi (5–30ms): used first when devices share a local network • Internet via WebSocket (30–140ms): auto-switches when devices aren't on the same network • Independent mode: if all connectivity fails, each device keeps running from its NTP anchor — recordings merge automatically when the connection restores A brief "Reconnecting…" banner appears. The stopwatch never pauses. NO ACCOUNT REQUIRED Create a room and share the 6-character code by voice, chat, or QR scan. Participants join in seconds. No sign-up, no password, no email address. When the session ends, the room disappears. UNDO OR DELETE A LAP Recorded the wrong lap? Tap Undo right after it's logged (can be turned off in Settings), or long-press any lap — or swipe in the full lap list — to delete it. The host can delete any lap; participants can delete their own. Deletions sync to every device. HANDS-FREE LAP RECORDING Record laps without touching the screen: the volume buttons, a Bluetooth shutter remote, or a keyboard/page-turner remote. Optional and off by default — turn it on in Settings. LIVE ACTIVITY Watch the running stopwatch right on your Lock Screen and in the Dynamic Island. Optional — turn it off anytime in Settings.
