Etar Calendar

Etar (from Arabic: إِيتَار) is an open source material designed calendar made for everyone!

Why?

Well, I wanted a simple, material designed and state of the art open source calendar that anyone can make better.

Special thanks

The application is an enhanced version of AOSP Calendar. Without the help of Free Software for Android team, this app would be just a dream. So thanks to them!

Features

• Month view.
• Week, day & agenda view.
• Uses Android calendar sync. Works with Google Calendar, Exchange, etc.
• Material designed.
• Support offline calendar
• -Agenda widget.- (disabled until #373 and #374 are fixed. Use Calendar Widget as an alternative.)

How to use Etar

Store your calendar on the phone only:

• Create an offline calendar.

Sync your calendar to a server:

• A cloud-synched calendar could be a google calendar, but you can also use any other public Caldav-server or even host your own (which would be the only way to keep full control over your data and still have ONE calendar usable from different devices.) To sync such a calendar to some server you need yet another app, e. g. DAVx5. That’s necessary because a Caldav client isn't included in Etar.

The following link provides a tutorial how to use Nextcloud + DAVx5 + Etar.

Technical explanation

On Android there are "Calendar providers". These can be calendars that are synchronized with a cloud service or local calendars. Basically any app could provide a calendar. Those "provided" calendars can be used by Etar. You can even configure in Etar which ones are to be shown and when adding an event to which calendar it should be added.

Important permissions Etar requires

• READ_EXTERNAL_STORAGE & WRITE_EXTERNAL_STORAGE
  ->import and export ics calendar files
• READ_CONTACTS
  ->allows search and location suggestions when adding guests to an event
• READ_CALENDAR & WRITE_CALENDAR
  ->read and create calendar events
