Windows focus timer

Dim everything except the window that matters.

Pick the window you need. The rest of the desk goes dark until Stop or a break. Other apps keep running. You just cannot work in them.

One 12 MB file. No installer. No account. 15 minutes of dimming a day, then $24 once.

Excel stays bright. Word and a terminal sit dimmed behind it. The OnlyThis timer is on the desk.

Excel stays lit. Word and the terminal do not.

One app stays lit

The others go dark.

Stay in the window you picked

Stop or a break lifts the smoke.

No network in the app

Nothing to phone home with.

Windows 10 and 11

A desk app. Not a tab.

Blocklists are infinite. The window you need is not.

Timers measure attention. They do not protect it. Blockers ask you to list what to forbid, which is always out of date. Slack is the job tomorrow and the distraction today.

OnlyThis asks for the one thing you need. Everything else dims. You stay in the windows you picked until Stop or a break. Other apps are still there. They are just dark and out of reach.

One thing lit. Everything else in the smoke.

Built for Windows knowledge work: a document, a spreadsheet, or a single browser window. Not a site blocker. Not a phone app.

Picker

Name the windows you need. Keep more than one.

An Alt-Tab style grid with real icons. Click Word. Click Slack if you are on a call. Confirm with Keep. One window stays bright. The others dim.

Window picker with Report.docx selected. Discord, Files, Slack, Notes, Capture, and Editor are the other windows.

Timer

A clock that stays on the document.

25 or 50 minutes of work. 5 or 10 minute breaks. Type any other length in Settings. Start, pause, and stop sit on the card. Ocean, rain, or brown noise if you want sound that never loops.

OnlyThis timer at 25:00, idle, with Start, Pause, Stop, and 25 or 50 minute focus lengths.

Settings

Dim on work. Lift on break. Mute the banners.

Auto-dim when a work interval starts. Clear the curtain for the break, or leave it up. Optionally mute Windows notification banners for the session, then restore them when you quit.

Settings for focus and break length, auto-dim, lift on break, and mute notification banners.

Three steps. Then the desk is quiet.

  1. 01

    Pick a window

    Click the target row. Choose one window, or several. Double-click to keep just that one.

  2. 02

    Start a block

    Press Start, or Space. The desk dims. Pause freezes the clock. Stop clears the dim and resets.

  3. 03

    Work, then break

    When work ends, the dim lifts for the break. When the break ends, work starts again. Stop whenever you want.

Stay in the window you picked.

We do not uninstall the apps. They keep running and still get their messages. You cannot work in them until Stop or a break. If you need a lock you cannot undo, use a blocker. If you just need a clock, a free timer is enough.

Questions

What happens after 15 minutes?+

The smoke lifts and the clock pauses. The timer still works. Dimming comes back the next day. A $24 key removes the daily cap. Paste it in Settings and press Activate.

Does it block websites?+

No. Slack and the browser stay installed and keep running. You cannot work in them during a block unless you picked them. Hit Stop if you need out. If you need a lock you cannot undo, use a blocker.

Can I still Alt-Tab?+

The switcher can still appear. Dimmed apps stay under the smoke, so you cannot land in them. You stay in the windows you picked until Stop or a break.

Can I keep more than one window lit?+

Yes. A document and the chat you are on a call in, or an editor and the browser you are testing. The last window you pick comes to the front.

Is there a Mac version?+

Not in this release. Windows 10 and 11 only.

Do you store my work?+

No. The app has no networking code. Settings live on your PC. Picked windows are not saved.

Windows says it protected my PC.+

The file is signed. A new download can still trip that warning until Windows has seen it run. Click More info, then Run anyway. The warning is about a new file, not a failed scan.

Is this an ADHD treatment?+

No. It is a desktop tool for people who lose the thread when other windows stay bright. It is not medical advice.
