A real timer, right here on the page: pick 25, 50 or 75 minutes or set your own length, press Start and work. The countdown also shows in the browser tab title, a discreet sound alert goes off at the end, and you can keep an ambient sound playing underneath. Free, no sign-up.
The countdown reads the device clock, so it stays accurate even if you leave the tab in the background or switch to another app.
The core idea is simple: pick one thing to do, set a timer, and while the timer runs you do nothing else. When it rings, you get up. The value isn't in the number twenty-five, it's in deciding the start and the end in advance rather than by how you feel in the moment.
Long sessions are not more serious than short ones. If twenty-five minutes feels like a lot, the method isn't the problem: the task simply isn't defined clearly enough yet.
A timer tells you how long you sat down. That's useful, but it isn't the same as knowing how much you got done: two distracted hours and one genuinely focused hour look identical in any count of minutes.
Inside FocusSea the maths is different. At the end of a session you rate your focus from 1 to 10, and the session is worth minutes times focus divided by ten: those are weighted hours. An hour at focus 5 is worth half an hour, an hour at focus 9 is worth almost a full one. It's an uncomfortable number, and that is exactly the point.
Around that number there are stats by day and by subject, a year heatmap showing the days you really worked, and video coworking for when studying alone doesn't work.
Same lengths, same sounds, plus the focus rating, weighted hours and the history of your sessions. Free, no ads, data in the EU.

Twenty-five minutes is the classic value and the best place to start. Fifty or seventy-five work well for writing, projects and subjects where you have to rebuild context each time. The custom field is there if your rhythm is different.
A short beep generated by the browser, not an audio file: it fires instantly and stays discreet on headphones. Some browsers only allow sound after you interact with the page, and pressing Start is enough to unlock it.
It counts the sessions completed in this tab and goes back to zero when you reload the page. If you want a history that lasts, with stats and weighted hours, that lives in the app.
Yes, from the menu above: the same sounds as the study sounds page, rain, thunderstorm, coffee shop, waves, wind, fireplace, forest, plus white and brown noise. They loop and have their own volume.
