Multical

Multical connects Google, Outlook, and Apple iCal calendars, automatically updating each platform when an event is added or changed on any other. When a meeting is scheduled in one calendar, the corresponding time slot is marked busy across all linked calendars, preventing overlapping bookings for users who juggle multiple roles or employers.

The tool targets freelancers, consultants, and individuals with portfolio careers who maintain several work‑related calendars. Users can define which calendars participate in the sync, set filtering rules for events, and generate scheduling links that respect the combined availability. A unified “Portfolio View” presents a single calendar overview of all commitments, and access controls let users decide what information is shared and revoke permissions at any time.

Multical emphasizes privacy‑first design, storing no permanent event data and giving users full control over shared content. It is positioned as an experimental solution for people whose schedules span more than the typical two‑calendar, single‑job scenario.
