Synchrium is a shared countdown for people working apart. Everyone joins the same room, the same timer runs on every screen with no drift, and you work in silence. When it hits zero, cameras and mics can come up together for a short reunion. Then you go again.
No scheduling, no stranger matching, no account needed. The room is just a link you send to people you already work with. The camera is never required during focus, which is the whole point.
Free tier is 3 sessions a day with no signup. Pro is $5/mo for unlimited timers, private rooms, custom durations and a vanity URL. Team is $4 a seat for a shared workspace, dashboard and SSO.
Timing is server-authoritative, so clients render the clock but never own it. Video is peer-to-peer WebRTC and media never touches our servers. There is a REST API for rooms, webhooks and personal access tokens.
