The Filter Engine

Sharing a calendar with your spouse, team, or family? You don't need to see everything. Create filters to hide or dim events by title, description, location, time of day, or day of week. Hide your partner's medication reminders. Dim your coworker's focus blocks. Filter out all-day events from a noisy shared calendar. Your view, your rules.

Six Ways to View Your Schedule

Day, Week, Month, Year, Agenda, and List views. All support pull-to-refresh, smooth swipe navigation, and a Today button. Create custom calendar views to quickly switch between subsets like "Work Only" or "Personal."

Tasks Built In

Full task management that syncs with your calendar accounts. Due dates, priorities, subtasks, categories, and progress tracking. Tasks appear alongside events in your Day and Agenda views and on home screen widgets.

Natural Language Quick Add

Type "Lunch with Sarah tomorrow at noon at Café Roma" and the app parses it automatically. Access Quick Add from the app bar, a 1×1 home screen widget, or an app icon shortcut.

Powerful Recurrence

Daily, weekly, monthly, yearly — with intervals, end dates, and complex patterns like "second Monday of every month." Edit or delete a single instance, all events, or this and future events.

Event Templates

Save frequently-used events as templates. Create new events with one tap, pre-filled with title, location, duration, reminders, and recurrence.

Attendees & RSVP

See who's invited, their roles, and their responses. Accept, decline, or tentatively respond to invitations directly from the app.

Home Screen Widgets

Agenda, Compact, and Month widgets that respect your filters. Tap an event to open it directly. Configurable font sizes. A 1×1 Quick Add widget for instant event creation.

Import & Export

Open .ics files from email or file managers. Subscribe to public calendar feeds. Share single events or batch export multiple events.

Holiday Calendars

Built-in holiday calendars for 20+ countries across the Americas, Europe, Asia Pacific, and Middle East. Added as auto-syncing subscriptions.

Contact Birthdays

Automatically creates birthday events from your device contacts.

Weather Forecast

14-day forecast in Day and Week views. Free, no tracking.

Multi-Select Operations

Long-press to select multiple events. Batch delete, move to another calendar, or export.

Offline First

Create and edit events without an internet connection. Changes sync automatically when you're back online.

Privacy Focused

No analytics. No telemetry. No ads. Your calendar data stays on your device and syncs only to your own calendar accounts. We never see your passwords — Google and Microsoft use secure sign-in, and other credentials are stored in Android's secure keystore.
