User Reviews

Fossify Calendar is praised for its simplicity, privacy, open-source nature, and effective event/task organization with syncing support. Users appreciate its pleasant UI and absence of ads. Common issues include incomplete holiday events, reminder notifications not functioning properly, syncing problems causing data loss, and UI limitations such as no vertical scroll in month view. Some users are also bothered by purchase prompts despite the app being free. Overall, it is favored as a lightweight, functional calendar alternative with room for improvements in notification reliability and holiday/event features.

Pros

Simple, intuitive, and pleasant interface that is easy to use and organize tasks/events.
Free and open source with no ads and privacy-focused, no need to connect to Google accounts.
Sync capabilities with services like CalDAV, Baikal, Nextcloud and good event/task management.
Offers both events and tasks separation, and allows different calendar views including weekly view.
Lightweight and efficient, does not drain battery as much as some other calendar apps.

Cons

Reminder notifications sometimes fail to vibrate or appear, especially if device is off.
Holiday events are missing or incomplete for some locales; lack of local holiday support (e.g. Philippine holidays).
Some syncing issues leading to data loss or overwritten calendars when adding local calendars or syncing CalDAV calendars.
Lack of vertical scrolling in month view, making it difficult to browse weeks between months.
Request to buy prompt appears despite being free and open source; some users dislike payment handling via Google with stored card details.
