OneCalとは何ですか?

OneCal is a real-time multi-calendar sync tool that synchronizes multiple Google, Outlook, and iCloud calendars so users avoid scheduling conflicts, share individual or team scheduling links, and manage all calendars from a single interface while preserving privacy.

コア機能

  • Real-Time Calendar Sync

    Automatically detects and syncs calendar changes as they happen across connected calendars, with iCloud updates reflecting within up to 10 minutes.

  • Multi-Way Calendar Syncs

    Supports one-way or multi-way syncs between two or more calendars, including syncing one calendar to multiple destinations with independent configurations.

  • Scheduling Links

    Create and share individual or collective scheduling links for easy appointment and meeting bookings without back-and-forth communication.

  • Unified Calendar Interface

    Manage Outlook, iCloud, and Google calendars from a single mobile-friendly interface to create, update, delete meetings, join calls, and RSVP.

  • Privacy-Focused Sync

    Customizable event replication that can exclude titles or control detail level; only necessary data is stored and no calendar event data is stored, analyzed, or sold.

  • Team Plans

    Organization-wide plans enabling teams to sync calendars collectively.

    Tools to precisely configure what is synced between calendars, without modifying existing events; generated clones can be deleted when a sync is removed.
