One countdown. Every device. One alarm. TimerLync keeps a countdown in sync across every device in the room. Set the time once, and every phone, iPad, and Apple Watch shows the same remaining seconds — then alarms at the same instant. WHY IT STAYS IN SYNC Devices agree on a single end time using network time, then count down locally. Even if Wi-Fi drops or a device goes to sleep, the alarm still fires on schedule — it's scheduled ahead of time, not pushed at the last second. FAIR STARTS A 3·2·1 lead-in lands at the same instant on every screen, so whoever taps Start doesn't get a head start. BUILT FOR GROUPS • Create a room, share a code or QR — no account, no sign-in • The host starts; pause, +1:00 and reset can be opened to everyone • Co-hosts and host hand-off when you need to step away • Ready check: wait until everyone confirms before starting • Works nearby over Bluetooth/Wi-Fi, or across networks when you're apart FOR TALKS AND EVENTS • Stage View: a full-screen, big-digit display for the podium • Host messages: send "Please wrap up" to every screen in the room • When it ends: hold at 00:00, count the overtime, flash, or show the clock, set once for the whole room • Strong Alarm: rings even in Silent mode or Focus (iOS 26 or later) MORE THAN A TIMER • Sequences: Talk 10 min → Q&A 5 min, switching automatically on every device • Group Pomodoro: focus and break cycles the whole team shares • History: look back on what you actually ran • Live Activity and Dynamic Island — glance without unlocking • Apple Watch companion with its own alarm, even away from your phone • Lock Screen widget and Siri: "Start a countdown in TimerLync" SOLO WORKS TOO No room needed.
