OurCal

OurCal is a privacy-first shared calendar app built for coordinating life with people you already know — couples, families, friends, housemates, and small teams — in private groups of 2 to 100 members. It takes a different angle from Calendly: there are no public booking pages or meeting links. Instead, its scheduling layer is availability sharing inside groups, marking members' synced events as busy without exposing any details.

Each group gets shared color-coded calendars with event-attached chat, notes, and checklists, so files, photos, and decisions stay with the event they belong to. Calendars sync with Google Calendar, iCloud, Outlook, Yahoo, and AOL, and the app supports recurring events, reminders, and lock-screen widgets. Its headline differentiator is end-to-end encryption for calendars, messages, and attachments, paired with a strict no-ads, no-tracking policy.

OurCal is a native-app product — iPhone, iPad, Mac, and Vision Pro plus Android, with no web version. The base app is free, while a paid Plus tier unlocks encryption, larger and multiple groups, widgets, and priority support. It suits people who want ongoing calendar coordination with the same group rather than one-off appointment booking, and it reports over 100,000 users across 140+ countries.
