About CoTimer
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). GROUPS AND ALERTS Invite anyone into a group, switch multi-home or multi-team life, and turn on alerts so phones ring when timers fire (best-effort; permissions still apply). FREE FOR A LIMITED TIME Core product free for a limited time. Fair-use limits may apply. GET STARTED Account → group → short timer → invite. Watch responses light up live. IMPORTANT Not a medical device, medication manager, or emergency service. Notifications may be delayed by Focus, battery settings, permissions, or connectivity.
