A high-performance Android calendar UI library rendered entirely with Canvas instead of RecyclerView or ListView. It supports vertical and horizontal switching, week and month views, custom week start, custom animations, and hot-pluggable UI customization with fast rendering and low memory usage.
Use cases
- add a calendar picker to an Android app
- build a schedule view with month and week switching
- create an iOS-style calendar on Android
- render a year view calendar with range selection
- customize calendar UI with custom markers and animations
- display a low-memory calendar in a scrolling list
When to choose
- you need a highly customizable, performant calendar view on Android
- you want month/week/year views with smooth vertical and horizontal switching
- you need range selection or custom date markers
- memory and rendering performance matter for large date ranges
When to avoid
- you need a cross-platform (Flutter/React Native) calendar
- you need features from versions after 3.7.1, which are no longer open source
- you need a full scheduling or event-management backend, not just a UI component
