The focus timeryou actually want to finish

Start the timer and a blurred photo slowly comes into focus while you focus. Stop partway and it stays blurred.

Most focus timersjust count the time.

FocusDiffusion gives you a reason to focus. Only your focus develops the photo.

01

It arrives blurred

A friend sends a photo with a voice note and a short message hidden inside. It doesn't open the moment you get it.

02

It clears while you focus

Set your time and get into it. The longer you stay, the more the photo develops.

03

Only finishing opens the last part

A real reason to see it through, sitting right there on screen.

04

Open it, and keep it

The hidden voice and message unlock, and the photo stays in your collection like a print.

Stop partway andit stays blurred.

The only thing that brings it into focus is you.

Focus together

Not an app just for you

It doesn't open when it arrives. It only clears once you finish your own session.

Ways to focus

You don't need a friend for this

Most days you focus alone anyway.

Solo focus

Just you and the timer. Pomodoro for study and deep work.

Today's photo

A new one to develop arrives every day.

Animal focus

When you just want to start — a random one.

Send and receive

Send and receive photos that only open after you finish a session.

A growing collection

What you brought into focus stays

Not a streak counter — the time you actually spent focusing, quietly adding up.
