OurCal: Integrating Messaging and Shared Calendaring with End-to-End Encryption
A unified platform combining group scheduling with secure, event-specific communication threads.
1Unified Communication and Scheduling
OurCal addresses the fragmentation of group planning by integrating messaging directly into calendar events. Founder Ryan Brodie emphasizes that the core issue in shared scheduling is communication, not productivity. By creating dedicated chat threads for every event, the platform ensures that photos, files, and notes remain in context rather than scattered across external messaging apps.
2Advanced Security and Privacy
The platform distinguishes itself through ANSSI-certified end-to-end encryption, covering profiles, groups, calendars, and messages. This security architecture ensures that data remains private, with keys never leaving the user group. OurCal operates on a subscription model, explicitly rejecting advertising and data mining to maintain user control and ensure that personal information remains exclusively owned.
3Seamless Calendar Synchronization
Users can consolidate schedules from Google, Apple, and Outlook into a single interface. The app supports subscribed calendars, such as sports fixtures or school term dates, allowing for a side-by-side view of personal and shared commitments. This functionality effectively prevents double-booking by providing a comprehensive overview of all group members' activities and shifts.
4Natural Language Event Creation
Event management is streamlined through natural language processing, enabling users to create entries like 'Dentist Tuesday 3pm for an hour' instantly. This feature includes automated reminders and repeating events. Notably, the AI processing occurs entirely on-device, ensuring that no sensitive scheduling data is transmitted to the cloud, further reinforcing the application's commitment to user privacy.
5Multi-Group Management Capabilities
OurCal allows users to organize different facets of their lives—home, work, school, and social—into distinct groups. Each group maintains its own unique calendar, member list, and chat history. This compartmentalization supports up to 100 members per group, making it suitable for diverse use cases ranging from small families and couples to professional work teams.
6Cross-Platform Native Experience
The application is built as a truly native experience across iPhone, iPad, Mac, Vision Pro, and Android devices. This cross-platform compatibility ensures that groups remain in sync regardless of the hardware individual members utilize. The interface allows users to pinch to zoom between high-level overviews and granular event details for improved schedule visibility.
7Operational Utility for Professionals
The platform provides specific utility for shift workers, including nurses, paramedics, and hospitality staff. By sharing rotas within the app, members can prevent scheduling conflicts with family plans. Automated before-and-after updates for any calendar change ensure that all participants are immediately notified of modifications, eliminating the ambiguity often found in traditional group chat planning.
8Market Reception and Growth
With over 2,533 ratings and features by Apple, OurCal has established a significant user base across various demographics. Continuous development is evident, with new features released every few weeks, such as the October 2026 update for iPhone Duo. The product remains focused on providing a secure, ad-free environment for collaborative life management and scheduling.
