# OneCal

> Calendar sync, booking links and a unified calendar view

OneCal keeps Google Calendar, Outlook, iCloud and CalDAV calendars in step by copying events between them in real time, so a meeting on one calendar blocks the same time on the others. The same subscription includes one-on-one and collective booking links, a unified view for managing every connected calendar, and an AI assistant. There is no free plan: every account starts with a 14-day trial and then needs one of three per-user plans.

## Ways to pay less

- **2 months free with annual billing** (Annual discount): The pricing FAQ and billing docs say yearly billing gives 2 months free: $60, $120 or $300 per user a year against $6, $12 or $30 a month. The page's toggle labels this 20% off. Source: https://www.onecal.io/pricing
- **Discount for nonprofits and open-source groups** (Nonprofit): The pricing FAQ says OneCal provides a discount to non-profit and open-source organizations. It does not state the amount. Source: https://www.onecal.io/pricing

## Key features

- **Real-time calendar sync:** Copies events between Google Calendar, Outlook, iCloud and CalDAV calendars, one-way or multi-way, so each calendar shows the time as taken. Every plan allows unlimited sync configurations.
- **Privacy controls for synced events:** Choose which details are copied, such as titles, descriptions, participants, locations and meeting links. Clones can be marked private, and events can be excluded by color or category.
- **Scheduling links:** Unlimited one-on-one and collective booking links with buffers, minimum notice, custom questions, manual confirmation, workflows and embedding. Availability is read from all connected calendars.
- **Unified calendar view:** One interface for every connected calendar: create, edit and delete events, RSVP to invites, join calls, hide the clones made by sync and see when teammates are free.
- **AI Assistant and MCP server:** A built-in chat answers questions about your schedule and proposes changes to events, syncs and booking links, each applied only after you confirm. An MCP server connects Claude, ChatGPT or other MCP clients.
- **Team administration:** The plan table lists OIDC/SAML SSO, SCIM directory sync, audit logs, admin-managed accounts and a user provisioning API on every tier. The docs say several of these are enabled on request.

## Good for

- People whose work and personal calendars keep producing double bookings
- Consultants and freelancers holding calendars from several clients
- Teams that want calendar sync and booking links in one subscription

## Worth knowing

- There is no free plan. When the 14-day trial ends, syncs are paused, cloned events are removed and booking links are disabled until a plan is bought.
- Starter connects 2 calendars per user and Essential 5. Removing OneCal branding from booking pages and dedicated support need Premium.
- In the mobile apps, calendar syncs are view-only and booking links cannot be created or edited; that setup is done in the web app.
- The macOS app on the plan table is the iPhone and iPad app, which the App Store marks as designed for iPad and limits to Macs with an M1 chip or later.
