Who each one suits

Fossify Calendar

  • People who prefer open-source apps installed from F-Droid

Google Calendar

Worth knowing

Fossify Calendar

  • Android only; the Fossify project lists Android as its sole platform.
  • The app has no sync service or cloud account of its own. Syncing depends on accounts or calendar providers configured on the device.
  • Development is funded by donations, and help comes through a public issue tracker and community channels.
  • Google Play and F-Droid publish releases on their own schedules, so versions can differ between stores.

Google Calendar

  • The paid version is only sold as part of Google Workspace, which also includes Gmail, Drive and Meet.
  • Personal accounts and Business Starter get one booking page; extra schedules, payments and reminders need Business Standard or higher, or an eligible Google One plan.
  • Time Insights and working hours and location are limited to work or school accounts, and Time Insights can only be viewed on a computer.
  • No desktop app is listed; Google offers it on the web and as Android and iOS apps.

Key features

Fossify Calendar

Five calendar views
Day, week, month, year and event-list views, with event filters to narrow what is shown and controls for color, theme and display.
Recurring events and reminders
Events take times, durations, reminders and advanced repetition rules. Reminder sounds, looping audio and vibration can be customized.
Sync through device accounts
Calendar data can sync through accounts or calendar providers set up on the device, such as Google Calendar, Outlook, Nextcloud or Exchange. Fossify runs no sync service of its own.
Import and export
Calendars can be imported from and exported to files, which keeps the data portable and gives a way to back it up or move it to another app.
Holidays, birthdays and anniversaries
Holidays can be imported, and birthdays and anniversaries can be drawn from the phone's contacts if contacts access is granted.
No Internet permission
The app does not request Android's Internet permission, contains no advertising and sends no app data or usage records to Fossify.

Google Calendar

Appointment booking pages
Publish a page where others pick a time on your calendar. Eligible paid plans allow several schedules, Stripe payments, email verification and up to 20 co-hosts.
Shared and layered calendars
Create calendars shared with a team or a whole organization, and view several calendars together, color-coded by category.
Scheduling from Gmail with Gemini
On Workspace plans, Gemini in Gmail can suggest meeting times and add events detected in an email with one click.
Google Meet and attachments
Events can carry a Google Meet video link and attached files, so the call and its documents open from the invitation.
Time Insights and working location
Work and school accounts can see how much time goes to meetings and who they meet most, and can share working hours and location.
Tasks on the calendar
Items from Google Tasks appear on the calendar next to events.
