Focus with Hei · on the App Store

A cat sits while you work.

Focus with Hei is body-doubling with a cat instead of a productivity dashboard. Pick a room, set twenty-five minutes, and Hei sits at the window with you until it's done — a serif countdown, a breathing cat, a screen that stays awake and asks nothing of you. Pause if life happens; he'll wait. When the block ends he stretches, the day is counted, and that's the whole app. Hei really does sit like this while we work. Now he can sit with you.

Where it actually is

Focus with Hei is on the App Store. The button at the top of this page goes straight to its listing, where Apple shows what it costs where you are and everything that comes with it.

No iPhone to hand? The waitlist below still works — one email when there's news, and nothing else.

What it looks like

Honestly: the icon, and the session panel at the top of this page. The real screenshots are on the App Store listing, so rather than copy them here and let them drift out of date, here is the mark the app actually carries.

The Focus with Hei app icon: Hei, a black cat drawn in cream with mint-green eyes, sitting inside an almost-closed mint progress ring on a midnight-navy square.
The app icon — Hei, mid-session
What it costs

The whole timer is free, forever. Both of Hei's rooms — the midnight window and the rooftop — plus pause, the streak, the stats and the end cue. That is a complete app, not a demo with a countdown on it.

Focus Plus adds Tong supervising from her desk, Meow supporting you by napping, and every scene that comes later: $9.99/year, or $1.99/month if you'd rather try it a month at a time. Both renew until you cancel. Nothing you can already use will ever be moved behind that line.

US prices. Apple converts them for your country, and the price on the listing is the one you pay.

A quiet room and one block of work

Pick a room, not a workflow

Hei's midnight window or the rooftop, free forever. No projects, no tags, no weekly review — the setup is choosing where to sit and for how long.

A streak that's kind

One finished session counts the day. Giving up early is recorded honestly and held against no one, and your best run is remembered forever.

One notification, ever

The moment your session ends, even if you wandered off. No streak nags, no "we miss you" — an app that notifies uninvited has already lost the argument about your attention.

Quiet on purpose

Silent unless you ask. Each scene has one quiet music loop — soft Rhodes and rain at Hei's window, slow bells on the rooftop, a lo-fi groove at Tong's desk, a music box on Meow's cushion. It stays off until you tap it on, plays only while a session is on screen, and mixes with whatever else you're playing — so if you'd rather have purrs and rain, our sleep app Purr can run alongside it, and one of its rooms is already free in your browser.
