The service is cloud-based, so there is nothing to install, and the setup takes just a few minutes. Main features: • Calendar Synchronization: OneCal is the most advanced Calendar Sync software in the market. You can sync multiple iCloud, Google, and Outlook calendars in real time, so your availability is reflected everywhere and you never get double booked. Syncs can be one-way or multi-way, and you choose exactly which event details are copied, which keeps your personal life private. You can also exclude events from syncing by color or category, color-code the synced events, and add an identifier to cloned events so they are easy to recognize. Every plan includes unlimited sync configurations and unlimited synced events. • Scheduling Links: You can effortlessly manage your appointments, meetings, and events with our user-friendly Scheduling Links, and say goodbye to tedious back-and-forth communication. All plans include unlimited one-on-one and collective booking links. OneCal reads your availability from all of your connected calendars, so invitees only see times when you are truly free. Each link can be customized with meeting durations, time slot intervals, availability schedules, buffer times, minimum notice periods, and limits on how far in advance people can book. You can also ask invitees custom questions, require manual confirmation, show a custom confirmation message, and redirect invitees to your own page after they book. Booking pages can carry your own logo, they can be embedded on your website, and the Premium plan lets you remove OneCal branding completely. • Unified Calendar View: The Unified Calendar View lets you see and manage all of your iCloud, Outlook, and Google Calendars in one place. You can create, edit, and delete events, RSVP to invites, join meetings with one click, hide the clones created by OneCal Calendar Sync, and see when your teammates are available. Available on the App Store and Play Store.. • Mobile and Desktop Apps: You can use all of the OneCal features straight from your preferred device with our iOS, Android, and macOS apps. The mobile apps let you manage your calendar syncs, scheduling links, and calendars right from your phone. • Integrations: OneCal connects with the tools you already use. Zoom, Google Meet, and Microsoft Teams links are added to your bookings automatically, so every meeting is ready the moment it is scheduled. Through Zapier, you can connect OneCal to thousands of other apps using pre-built triggers and actions. • MCP Server: The OneCal MCP Server gives AI assistants like Claude and ChatGPT secure access to your calendars. Your assistant can list your events, check your availability, and create, update, or delete events for you. Built for teams and enterprises: • Admin Managed Accounts: Admins can fully manage the accounts of their team members, as long as each user allows it. • User Provisioning API: The API lets you programmatically invite users, remove users, retrieve existing team members along with their sync usage, and view pending invitations. • OIDC/SAML SSO: Your team can sign in to OneCal through your identity provider, such as Okta, Azure AD, or Google Workspace, using OpenID Connect or SAML. • SCIM Directory Sync: Team members are automatically provisioned and deprovisioned from your identity provider using the SCIM protocol. • Team management: Pricing is per user, team management is simple and intuitive, and team members can sign up on their own. • Dedicated support: Teams on the Premium plan get dedicated support through Slack or Discord, along with hands-on user onboarding assistance. Security and compliance: • OneCal is SOC 2 Type II certified and GDPR compliant, and a Data Processing Agreement (DPA) is included. • OneCal connects to your calendars through OAuth2 and never stores your passwords. All data is encrypted in transit and at rest. • OneCal does not store or analyze your calendar event data, and it only asks for the minimal permissions it needs to work. You can try OneCal free for 14 days, and no credit card is required. ## OneCal Pros & Cons **What users like:** - Users find OneCal incredibly **easy to use** , valuing its seamless calendar syncing and excellent support.
