Made a Pomodoro variant where the timer is shared across people "meet at zero" via audio and/or video (or not), free 3/day, no account needed, community break room always open

Classic Pomodoro but the countdown is synchronized across everyone in a room (server-side clock, no drift). Work interval in silence → at zero, optional cameras/audio for the break together → run it again. Presets for 25/5, custom durations, and a stopwatch mode. It's free (3/day, no account): https://synchrium.com.
