## What is TimerLync?

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

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
• Overtime: keep counting past 00:00 when a session runs long
• 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. Quick Timer is a plain countdown with the same reliable alarm.

TimerLync Pro (one-time in-app purchase) unlocks rooms of up to 8 devices and CSV export of session history. Rooms of 2 devices and joining any room stay available to everyone.
