Features:
* Month, week, day, quarter and agenda views
* A left drawer to show/hide and reorder your calendars, switch groups, and reach the menu
* Share calendars with other users and organise them in groups
* Birthdays: a dedicated birthday calendar with age and reminders, optionally imported from your contacts
* Per-setting cross-device sync — choose exactly which settings follow you across web, iOS and Android
* Fully customisable colours and a dark interface
* Event reminders / notifications

Calendarr requires access to a Calendarr server (self-hosted). Enter your server URL, then sign in.
