About this app

A focus timer you'll actually want to finish. Start the timer and a blurred photo slowly comes into focus while you concentrate — stop early and it stays a blur.

Most focus timers just count down. FocusDiffusion gives you something to focus for. Your attention is the only thing that develops the picture, so every minute you stay present is a minute you can see.

STAY FOCUSED

Whether you're studying for an exam, doing deep work, fighting procrastination, or just trying to stay off your phone, FocusDiffusion turns a plain focus timer into a session you want to see through.

- A focus timer with a pomodoro rhythm — set a length and concentrate
- A photo that sharpens the longer you focus, so there's a real reason to finish
- Stop early and the picture stays blurred — your focus is what brings it in

FOCUS, TOGETHER

FocusDiffusion isn't only for solo focus. Send a friend a photo with a hidden voice note and a short message. It won't open the moment they receive it — it only develops when they finish their own focus session. A small, kind reason for someone you care about to sit down and concentrate.

- Send a photo that unlocks only when your friend completes a focus session
- Hide a voice note and a message inside it
- Receive photos from friends and bring them into focus yourself

WAYS TO FOCUS

- Solo focus — just you and the timer, pomodoro-style, for study or deep work
- Daily photo — a fresh one to develop every day
- Animal focus — a random friend to bring into focus when you just want to start
- Send & receive — focus gifts that unlock on completion

A COLLECTION THAT BUILDS

Every photo you bring into focus is kept as a print in your personal collection — a quiet, growing record of the time you actually stayed present, not just another streak counter.

WHO IT'S FOR

Students who need a study timer or exam timer, people doing deep work or working from home, anyone managing ADHD or procrastination, and anyone who simply wants to put the phone down and concentrate.

FOCUSDIFFUSION PRO

Go further with voice messages — send your voice along with the photo — and free early finish, so you can reveal and keep a photo the moment you're ready. Start anytime, cancel anytime.
