50-minute timer
Free online countdown. No sign-up — just press start. Runs full screen and plays a sound when time is up.
A 50-minute timer for a block of deep work, a lesson or a workout. Put your phone away, choose one task and let the timer keep track.
Fifty minutes of work and a ten-minute break fill exactly one hour — a popular longer rhythm than 25-minute pomodoros for bigger tasks.
An alarm in 50 minutes
Need a reminder in 50 minutes, or a wake-up call after a short nap? Press Start, leave this tab open with the sound on, and it rings in exactly 50 minutes. The time it will ring is shown under the timer. In full screen most phones and laptops keep the screen awake; for a long sleep, your phone's own alarm is the safer choice.
Want to know what the time was for?
Give each task its own time and see when your whole list will be done. Free, no sign-up.

Questions
Does the timer keep running if I switch tabs?
Yes. It counts down against the real clock, so it stays correct in a background tab. Some browsers can't play a sound while the device is asleep.
Will it make a sound when time is up?
Yes. A soft chime plays when it reaches zero, as long as this tab is open and the sound is on. Press start once so your browser allows audio.
Can I link the time to a task?
Yes. In the free Todo & Timer app every task can become a focus round, and the time is saved to the task.
Can I use it as an alarm?
Yes, for short times. It rings when it reaches zero, as long as this tab stays open and the sound is on. Some browsers can't play a sound once the device is asleep, so keep the screen on (full screen does that on most devices). For a long sleep, use your phone's alarm.
