What are the best Material Design calendar apps for Android?

Calendar apps help plan out upcoming events. When choosing a calendar app there are a few key things to consider: how easy is it to add events, how it helps the planning process, how it helps keep track of everything and what helpful information it can present in each context.

Good apps will allow adding events quickly. Some apps even support natural language input that allows adding events in a conversational manner. For example, typing in “A meeting with Stuart Kearney at 2pm at Philz Coffee” will add an event and set the date and time.

They will provide an easy way of overviewing upcoming events by laying them out in a way that’s both intuitive and information dense. Most will offer homescreen widgets that will give an idea of upcoming events without having to open up the app.

Good apps will provide integrations with various third-party services that add contextual information. Information such as a getting directions to an event using a navigation service or automatically adding events from social networks or email.
