About Hokkori

Hokkori (ほっこり) is a Japanese word for the feeling of gentle warmth inside — the small glow of wrapping your hands around a hot mug on a cold day. There's no English word for it. We built an app around it instead.

Why a cozy timer?

Most productivity tools treat focus as a performance problem: streaks to defend, dashboards to optimize, ads between sessions. But for most of us the hard part of focusing isn't discipline — it's that sitting down to work feels cold. Hokkori starts from the opposite idea: make the place you focus somewhere you actually want to be. A warm pixel-art room. Rain on the window while the timer runs. Sound you mix yourself until it feels right. The pomodoro method does the structuring; the room does the inviting.

The whole room fits in 53 kilobytes

Hokkori is built with a small engineering obsession we call zero-asset: the room is hand-drawn SVG, and every ambient sound — rain, fire, wind — is synthesized live in your browser with the Web Audio API. No video backgrounds, no downloaded sound packs. The entire app ships in about 53 kB gzipped, smaller than most sites' cookie banners. That's why it loads instantly, works fully offline as an installable PWA, and runs happily on old laptops and bad connections.

What we promise

• Free, no ads, ever. Ads are the direct negation of calm. If Hokkori helps you, you can buy us a coffee — that's the entire business model.
• No account, no tracking. Your stats, streaks, and settings live in your own browser. You can export your data anytime, and we never see it.
• Simplicity is a feature. Every addition has to earn its place in the room. We'd rather be small and loved than large and tolerated.

What's next

The long-term dream is ambient presence: the quiet company of other people focusing around the world — a count of candles lit right now, never webcams, never leaderboards. Cozy first, together softly.
