About Fossify Calendar
Fossify Calendar is a clean, ad-free calendar for Android from the Fossify project, the community fork that keeps the well-known Simple Mobile Tools apps maintained and open source. It lets you plan your days without accounts or tracking: events can stay only on your phone, or you can sync them with online calendars such as Google or Nextcloud through CalDAV.
You can switch between day, week, month, year and agenda views, colour-code events, set repeating events and reminders, and add home-screen widgets. Calendars can be imported and exported as .ics files, and national holidays can be added in a few taps. The look follows your own colours, and a dark theme is built in.
