KashCal
What KashCal is
KashCal is a free, open-source Android calendar app from OneKash Labs for bringing calendars from different services into one place. It supports direct iCloud and CalDAV synchronization, ICS subscriptions, and calendars already on an Android device. The maker lists Nextcloud, Fastmail, Radicale, Baikal, Stalwart, Zoho, SOGo, and mailbox.org as CalDAV providers. Google and Outlook calendars can appear through Android device calendars or ICS feeds. Views include Agenda, Day, 3 Days, Week, Month, Month (Full), and Year. Smart event add turns plain-language text into an event with a date and time. Reminders, contact birthdays and anniversaries, widgets, full-text search, on-device Insights, and 67 languages are included. Beta two-way contact sync supports iCloud and other CardDAV servers, including photos. The app stores calendar data on the device and uses no account, tracking, analytics, or KashCal servers.
