Google has added the Google Calendar Android app to Google Play. In the past, it has only been available for select devices like the Nexus S and Galaxy Nexus.
The app comes with the ability to snooze events directly from notifications and use predefined messages to send quick updates to even participants directly from notifications. You can also pinch to zoom in and out of days and set home time zones.
"In addition, we also expanded the sync period so you can review past events from up to one year ago directly on your device," says Google's Michael Chan.
All of this is in addition to the requisite creation, editing and deleting of events and the ability to respond to invitations, of course.
It's only available for devices running Android 4.0.3 or later.
There are some issues with HTC devices that Google acknowledges in the Google Play store. Day and week views may not work with some of them. Notes and pictures may be removed from all calendar events, but will still be available in HTC's Notes app. Local unsynced events may be lost after installing the Google Calendar app, and touching an email invitation in a mail app opens Calendar in the browser rather than the app.
