Run multiple named timers simultaneously for cooking, workouts, or project tracking.
Multi Timer keeps several labeled countdowns visible at once, so unrelated durations can overlap without being confused. Enter a name and duration for each activity, then run the timers during the same period. Each countdown represents its own remaining time; the name identifies the activity but does not affect the calculation. The common misread is that "parallel" means synchronized. It only means the timers can run concurrently. Timers started at different moments will not share the same elapsed time, even if their original durations match.
A concrete input and expected output from the current implementation.
Input
Tea: 5 minutes Eggs: 8 minutes Start both together and let them run for exactly 2 minutes.
Expected output
Tea: 3 minutes remaining Eggs: 6 minutes remaining
Both countdowns lose the same two minutes because they started together. Five minus two leaves three, while eight minus two leaves six.
Create one countdown for each activity by pairing a clear label with a duration. Labels let you tell simultaneous timers apart while several values are changing. The duration is the full interval assigned to that entry. Adding another timer does not divide, extend, or otherwise alter the first timer; each retains its own target.
While timers overlap, each remaining value changes according to that timer's own start and elapsed time. Two equal-duration timers started together remain equal. Starting one later preserves an offset between them. When a shorter countdown reaches zero, that event applies only to that named interval; longer timers can still have time remaining.
Yes. Independent labels and durations are the point of Multi Timer. A three-minute countdown and a ten-minute countdown can overlap, and reaching zero on the shorter one does not determine the longer one's remaining value. For a precise relationship between them, start each at the intended moment and read each entry separately.
No. Multi Timer is a visible browser-based countdown, not a guarantee that a completion cue will reach you after the page is closed or the device is unavailable. Audio, notifications, sleep, and tab behavior can vary by browser and settings. For safety-sensitive cooking, medication, or equipment, keep supervision or an independent alarm in place.
