Quiet Moss Studio
We make apps that put your mind in airplane mode.
And from time to time, some weird stuff.
Quiet Moss is a small independent studio. We build software that helps you focus — plus stranger experiments we can’t help making, like Long Haul, a truck-sim web game you play to zone in.
Studio notes a few times a year — new tools, new oddities. No spam, unsubscribe anytime.
Focus tools
Software that helps you drop into deep work and actually stay there. Setsudo is the first of a small family.
Weird experiments
Strange little games and oddball ideas — like a truck-sim built for focus. We make them because we want to.
Made to last
No subscriptions to chase, no churn to optimize. We build tools we want to keep using for years.
Long Haul
A truck simulator you play to focus.
Pick a route, settle in, and drive. No score, no timer, no pressure — just the road, the engine hum, and a slow horizon. It’s a focus game disguised as a truck sim, free to play in your browser.
Play on itch.io
Setsudo
A calm, distraction-free focus timer.
Set an intention, start a quiet session, and let everything else fall away. Gentle timers, soft soundscapes, and nothing extra. In progress now — launching soon.
