Inbox Focus.

One email at a time.

Inbox Focus shows you only the oldest (or newest) message in your Gmail inbox and quietly hides everything else. When you handle it, the next one appears. That's the whole app.

Three knobs.
That's it.

Inbox Focus is a single page of preferences and a toggle. I don't track anything. There's no account. There is nothing to sign up for.

Why we built it

The inbox is a list of every interruption anyone has ever sent you, sorted by recency. I didn't like that. Inbox Focus shows you the next email you need to handle, and only that. When it's done, the next one appears. If two minutes of staring at one email feels long, it's because two minutes is, actually, a long time.

FAQ
Does it work outside Gmail?

Not yet, and probably not ever. I made it for the Gmail web inbox because that's where I kept losing my afternoons.

Does it read my email?

No. Inbox Focus runs entirely in your browser and only manipulates which rows are visible in Gmail's interface. Nothing leaves your machine.

Will it stay free?

Yes. It's small enough that giving it away costs me nothing. If you'd like to say thanks, try Snipflux.
