KashCal

Your calendars are everywhere. Family on iCloud. Work on the phone calendar. Holidays from some website. Birthdays buried in your contacts. KashCal pulls them into one app on Android.

Sync iCloud directly. No workaround needed. Connect any CalDAV server: Nextcloud, Fastmail, Radicale, Baikal, Zoho, mailbox.org, Posteo, Stalwart, SOGo, and others. Subscribe to ICS feeds for holidays, school terms, and sports seasons. See your phone's built-in calendar alongside everything else. Birthdays pull from contacts automatically.

Quick Add turns 'Coffee with Kash tomorrow 3pm' into an event. Handles dates, times, recurrence, and locations. Insights show where your time goes. Busiest days, back-to-back streaks, free blocks. All computed on-device. Home-screen widgets put your day at a glance. Six views with pinch-to-zoom and drag-to-reschedule. Available in 67 languages.

Private by default. Credentials encrypted with Android Keystore. No analytics. No telemetry. No KashCal account. Events stay in a secure database other apps can't read. We have no servers. There is nothing to collect.

Funding goes to the work. CalDAV compatibility testing across iCloud, Nextcloud, Fastmail, Radicale, Baikal, Zoho, mailbox.org, Posteo, Stalwart, SOGo, and others. RFC 6638 scheduling so meeting invitations work end-to-end. Translation upkeep across 67 languages on every release. Faster background sync. Steady release cadence.
