Deep work without a 25-minute cut-off
Pomodoro ends the session for you. Here it ends when you decide, and the length is recorded either way.
Focus
A focus timer that lasts as long as you do
Full screen, ambient music, and the sites that usually win are closed for the duration. When you stop, the session is written down.

Distracting sites stay shut while the timer runs.
Counted on your device
Nothing about this visit left your browser.
Time to wind down
Breathe with the circle until the screen lets go.
Rain over the page
Ambient sound, nothing blocked.
Look 20 feet away
Twenty seconds. Your eyes have been at this screen for two hours.
Three things today
Written this morning, still waiting.
Today you are the Learner
Every tab is a vote for who you are becoming.
Dark, without the mess
Images keep their colours. Already-dark sites are left alone.
25 on, 5 off
The rhythm runs itself; you stop watching the clock.
Warm after sunset
The page warms up in the evening instead of glowing at you.
Two minutes
In, hold, out — follow the circle and go back to work.

on
click the toggle — this is the real interface, not a screenshot
Twenty-five minutes is someone else’s number. Deep work does not arrive on a schedule.
How it works
Press start, and the browser gets out of the way
No timer to negotiate with, no tab to keep alive.
01
Start the session
The screen clears to a single space with the player and a running clock.
02
Music, if you want it
Neoclassical and Ambient are free. Lo-Fi, Chillhop, Synthwave and Future Garage come with Pro.
03
Distractions stay shut
Sites on your blocklist stay closed while the session runs, without setting anything up again.
What you get
Inside a focus session
No fixed length
Pomodoro cuts you off at twenty-five minutes. Here the session ends when you end it.

Built-in player
The music lives in the extension, so there is no separate tab to lose or accidentally close.
free
Six genres
Neoclassical and Ambient free; four more with Pro.
free
Live spectrum
The sound is drawn as it plays — a quiet signal that the session is still running.

How long you actually held focus, counted on your device.

Common cases
What a focus session is used for
Study sessions with background music
Neoclassical and Ambient are free. The player is inside the extension, so there is no tab to lose.
Blocking distractions only while working
Your blocklist activates for the duration of the session and releases when it ends.
Music for concentration without YouTube
No video tab, no autoplay of the next thing, no adverts in the middle of a thought.
Seeing how long you actually focused
Every session is timed and written down, on your device.
What a session leaves behind
The length of the session is written to storage in your own browser. We do not receive it, and we do not receive what you were working on. Music is streamed, so the audio files are fetched — nothing about your session is attached to that request.

About Focus
Is this a Pomodoro timer?
No. Pomodoro fixes the session at twenty-five minutes; here you decide when to stop. The session is timed and recorded, but never cut short for you.
Do I need an account to use focus mode?
No. It works immediately after installing, and your session history stays on your device.
Which music is free?
Neoclassical and Ambient. Lo-Fi, Chillhop, Synthwave and Future Garage are part of Pro.
Does it block sites automatically?
Yes. While a session runs, the sites on your blocklist stay closed, so you do not have to switch on the blocker separately.
The other eleven
They work together, not instead of each other
Focus is one of twelve modes
Blocking, screen time, dark mode, sleep and eye care come in the same extension, free.
