OneCal Overview
OneCal is a comprehensive calendar automation and synchronization platform designed to eliminate scheduling conflicts and streamline time management for individuals and teams. By seamlessly syncing multiple calendars from Google, Outlook, and iCloud in real-time, OneCal ensures your availability is always accurate and up-to-date across all your personal and professional accounts. This prevents the common issue of double bookings that arises from managing disparate schedules. The platform is built with a strong focus on privacy and security, allowing users to control exactly what event information is shared, from full details to simply showing a 'Busy' block.
Beyond synchronization, OneCal offers powerful scheduling features. Users can create and share customizable booking links for one-on-one or team meetings, eliminating the tedious back-and-forth emails typically required to find a suitable time. The unified Calendar View provides a single, consolidated interface to see all your commitments at a glance, further simplifying schedule management. Trusted by thousands of professionals from companies like Product Hunt, OneCal is praised for its intuitive user interface, robust performance, and exceptional customer support.
How to use OneCal
Getting started with OneCal is a straightforward process designed to have you syncing calendars in minutes:
- Sign Up for a Free Trial: Visit the OneCal website and sign up for a 14-day free trial. No credit card is required to start.
- Connect Your Calendars: Securely connect your Google, Outlook, and iCloud accounts using the official OAuth2 authentication. OneCal never sees or stores your passwords.
- Create a Sync Configuration: From the dashboard, click to start a new sync. You can choose a one-way sync (from a source calendar to a target) or a multi-way sync to keep two or more calendars perfectly aligned.
- Customize Sync Settings: Select the source and destination calendars. Crucially, configure the privacy settings. You can choose to sync all event details (title, description, participants) or mask them to only show 'Busy'. You can also assign custom colors to synced events for easy identification.
- Automated Syncing: Once configured, OneCal works in the background, automatically syncing new events and updates in real-time. There's no need to keep the app open.
- Create Scheduling Links (Optional): Navigate to the Scheduling Links section to create personalized booking pages for individuals or teams. Customize your availability, meeting duration, and branding.
- Use the Calendar View: Access the Calendar View to see all your connected calendars in one consolidated, easy-to-read interface.

- Multi-Way Syncing: Set up one-way or multi-way syncs between two or more calendars with a single configuration.

Use Cases for OneCal
OneCal is ideal for anyone juggling multiple calendars:
- Consultants and Freelancers: Manage separate calendars for each client (e.g., a client's Google Workspace and another's Office 365) and consolidate them into a master calendar to avoid conflicts.
- Professionals with Multiple Roles: Keep a work calendar, a personal calendar, and a side-project calendar in sync without manually duplicating events or sharing private details.
- Sales and Business Development Teams: Use collective scheduling links to show the combined availability of a team, making it easy for prospects to book demos or calls.
- Executives and Managers: Provide a clear view of their true availability to assistants and team members, even when schedules are spread across different platforms.
- Anyone Seeking Work-Life Balance: Automatically block off personal appointments in work calendars (and vice-versa) privately, ensuring personal time is respected without revealing details.
Advantages of OneCal
