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.
