Particle, the study planner that counts time instead of debt

Field notes

Particle describes an exam planner that distributes work backward from a deadline rather than measuring an outstanding task backlog. Its social layer uses a shared clock: squad members can see when one another are studying, join a session, or disappear from view. A separate link can carry lectures, labs, rooms, and syllabus dates into a classmate’s app without an account. The page also states that contacts, tasks, notes, and hours remain uncollected, with no ads, trackers, or analytics SDKs.
