• Reminders stay reliable on busy calendars; month widget fixed on busy months (#373)
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 on Android.

• iCloud: switched to Android but your family is still on Apple? Sync iCloud calendars directly. No bridge, no workaround.
• CalDAV: Nextcloud, Fastmail, Radicale, Baikal, Zoho, Mailbox, Stalwart, SOGo, and more. Native two-way sync, no middleware. Your phone's Google and Outlook calendars show up too.
• Seven views: month, full-height month, agenda, day, 3-day, week, and year. Pinch to zoom the timeline, drag an event to reschedule it.
• Smart Add: type "Coffee with Kash tomorrow 3pm" and it's added to your calendar. Understands dates, times, recurrence, and locations.
• Scheduling: invite people, send meeting invitations, and RSVP to invites others send you.
• Insights: see where your time goes. Busiest days, back-to-back streaks, free blocks. Computed on-device.
• Widgets: keep your day on the home screen without opening the app. Agenda, date, week, month, and upcoming.
• ICS subscriptions: follow any calendar feed. Public holidays, school terms, sports seasons.
• Birthdays & anniversaries: pulled from your contacts automatically.
• Per-event colors: from a curated palette or a full color wheel, so your week reads at a glance.
• Make it yours: light, dark, or system theme, plus a KashCal Teal palette. Supporters can switch to a special app icon.
• Accessibility: full screen-reader (TalkBack) support, and set the app's language right from Android settings, in 67 languages.
• Works fully offline out of the box.
Private by default
No analytics. No telemetry. No KashCal account. We have no servers, so there is nothing to collect.
• Credentials encrypted with the Android Keystore
• App lock: hide your events behind your fingerprint, face, or screen lock
Free as in speech. Also free as in beer.
