⏱️ Free Online Multi Timer — Stopwatch, Countdown & Alarm Clock

Ever tried to time a workout, a Pomodoro session and an oven countdown all at once using your phone's clock app? Slim ABBAR and Hafedh KHAYATI built this page for exactly that frustration — a precise stopwatch (0.01 s), a flexible countdown timer and a musical alarm clock, all in one tab. No download, no registration, nothing collected.

What you can do on this page:

  • Time any activity with a precision stopwatch (centiseconds).
  • Protect your focus with a countdown timer (Pomodoro, exams, breaks).
  • Schedule alarms for wake-up, medication, meetings or school pickups.
  • Use your own MP3 sound for the alarm or keep the default melody.
  • Combine tools: alarm for wake-up + timer for exercise + stopwatch for tasks.
Quick start: use the stopwatch for open-ended timing, switch to the countdown timer for focus blocks or cooking sessions, then use the alarm clock when you need a fixed alert at an exact hour with your own sound or the default melody.

⏱️ TOOL 1 — Online Stopwatch (0.01 s Precision)
