Shared Timer vs CoTimer

The iPhone Clock app can't share a timer, and the apps that can go quiet the moment the ringer is off. Shared Timer fixes both: set it once, send the link, and every phone rings at the same second, even on silent. HOW IT WORKS 1. Set a timer, by duration or by picking an exact time ("dinner's out at 6:15"). 2. Share the link through Messages, WhatsApp or any app you already use. Recipients just tap and they're in. No sign-ups. 3. Ring together. Every device rings at the same absolute moment, even offline, with the app closed or with the phone on silent. 4. Change it while it runs. Edit the time, name or color, or add a minute with one tap, and every phone follows. RINGS EVEN ON SILENT On iOS 26, every countdown in Shared Timer is a system alarm, the same kind the Clock app uses. The Silent switch doesn't mute it. Do Not Disturb and other Focus modes don't hold it back. Your iPhone sounds and shows a full-screen Stop button, whether the app is open, closed or the phone is locked, and it keeps ringing until you stop it. No more missed timers because the ringer was off. On iOS 17 and 18, timers alert with a notification instead, which follows your Silent switch and Focus settings. EVERY TIMER IS ITS OWN ALARM Run the pizza, the laundry and the nap at once. Each timer is scheduled as its own alarm, so stopping one never silences another. Change a timer or add a minute and its alarm moves with it, on every phone sharing it. When a timer rings or you stop it, its Live Activity clears itself from the Lock Screen and Dynamic Island. Nothing to swipe away, nothing left ringing at the wrong time. OR TIME ANYTHING, LIVE Count-up timers work like a shared stopwatch: for naps, workouts, study sessions, anything. Everyone you share with watches it tick and sees how long it ran. WHY PEOPLE USE IT • Kitchen coordination: "Dinner's out at 6:15," and every phone in the house knows it. • Game nights and watch parties: sync the start so nobody misses kickoff. • Workouts and study sessions: start an interval together, even from across the country. • Kids and chores: "Screen time ends at six," backed by an alarm instead of an argument. • Meetings and calls: a countdown to "go time" the whole group can see. • Long distance: "Call me the second this hits zero."

CoTimer is the shared clock for any group—families, partners, roommates, small teams, corporate pods. One timer. Many phones. Start it when something starts. Whoever can take it marks Done; who can’t marks Can’t so someone else steps in. Live status plus a log of what actually happened—without forcing a plan weeks in advance. BUILT FOR LOW PLANNING, LOW COMMITMENT No shift board required. No long “who’s on laundry this month?” setup. Start a shared countdown in the moment and let convenience decide. Perfect when you want things done now more than you want a schedule. ESPECIALLY HELPFUL WITH A BABY (AND SHARED CARE) Couples use shared timers for sleep stretches, feeding or bottle windows, pump reminders, and medicine intervals so both see the same clock and history—coordination only, not a medical product. Less 3 a.m. “did you already…?” friction. ALSO HOMES, HOUSES, AND WORK Oven and laundry, roommate handoffs, desk coverage, “ping me in 20,” ops and kitchen steps—anywhere a small group needs a shared end time without project software. TIMERS, ALARMS, STOPWATCHES Countdowns and alarms for shared end times. Stopwatches for elapsed time the whole group can see—same status chips and history. LIVE STATUS ON EVERY TIMER Status chips: Done, Can’t, Snoozed, ringing—so nobody’s guessing in chat. • Can’t — hand off live when you can’t take it • Snooze for everyone — move the shared end time • Remind me only — personal nudge, shared clock stays put HISTORY AND RUN LOGS Filter by timers, alarms, or stopwatches—and by Done, Missed, Snoozed, and Can’t. Expand a run for started → snoozed/can’t → finished (or missed).
