Caffeinated Calendar aggregates all your calendars in one place and lets you filter out the events you don't need to see.
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 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. A Quick Add widget for instant event creation.
