Synchrium is a shared countdown for people working apart. Start a session, send the link: the same timer runs for everyone (server-authoritative, no drift). You focus in silence: at zero, cameras come up together for a short reunion. Then go again. No scheduling, no stranger matching, no account needed. Camera is never required during focus. Free: 3 sessions/day. Pro $5/mo adds unlimited timers, private rooms, custom durations, and Gathering, an optional video huddle before focus starts.

Hey PH 👋 I built Synchrium after realizing my best focus sessions were the ones where someone else was quietly working nearby, even virtually. It's a shared countdown: everyone focuses in silence, and at zero, cameras come up together for a short reunion. No scheduling, no matching, no account needed: start a session and share the link. Camera is never required during focus (that's the point). Free: 3 sessions/day. Pro ($5/mo) adds unlimited timers, private rooms, custom durations, and the new Gathering, an optional video huddle before focus starts, for teams that want to state intentions first. Would love your feedback on the reunion ritual, it's the part people either love or don't get until they feel it.

Synchrium

Focus alone. Meet at zero.
