All your calendars in one app. iCloud, CalDAV, device, ICS. Private.

Your calendars are everywhere. Family on iCloud. Holidays from some website. Birthdays buried in your contacts. Work on the phone calendar. KashCal pulls them into one app.
• iCloud: Switched to Android but your family is still on Apple? Sync with iCloud calendars directly. No workaround needed.
• Quick Add: type "Coffee with Kash tomorrow 3pm" and the event is created. Handles dates, times, recurrence, and locations.
• Insights: See where your time goes. Busiest days, back-to-back streaks, free blocks, and more. All computed on-device.
• Widgets: Check your schedule without opening the app. Agenda, date, week, and month.
• CalDAV: Nextcloud, Radicale, Fastmail, Baikal, and others. Native sync, no middleware.
• Device calendar: See events from your phone's built-in calendar alongside everything else.
• ICS subscriptions: Subscribe to any ICS calendar URL. Public holidays, school terms, sports seasons.
• Birthdays & anniversaries: Pulls from your contacts automatically.
• Local: Don't need sync? Works fully offline out of the box.
Private by default
No analytics. No telemetry. No KashCal account. Your data stays on your device.
• Encrypted credentials
• Fort Knox Mode: other apps can't read your events
Free as in speech. Also free as in beer.
WhatsNew:
• Fix biweekly recurrences with Sunday selected: events on Sun/Tue/Thu starting Sunday now appear in the same week
• ICS export: stricter RFC 5545 compliance for cross-app calendar imports
• Monthly view: past-event dimming refreshes when you reopen the app
• Widgets: improved day-header contrast on light and dark backgrounds
Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos.
