- sync my phone calendar with google calendar and nextcloud
- add a customizable calendar widget to my home screen
- import birthdays and holidays into my calendar
- manage recurring events with flexible repetition rules
- replace a proprietary calendar app with a privacy-respecting foss alternative
- filter and switch between daily, weekly, monthly, and yearly calendar views
When to choose
- you want a private, ad-free calendar on Android with no unnecessary permissions
- you need widgets, themes, and multiple calendar views in a lightweight app

When to avoid
