In Today Calendar, you can alternate between different views very easily, moving between the daily, weekly, and monthly views with just a gesture on the screen. Likewise, entering an event or appointment is quick and easy.
When creating a new event, you can add the place, time, people going, and so on. Basically, this app has all the same features as Google Calendar, only with a more elegant interface.
Today Calendar is a good calendar app that improves upon the default Android calendar. An interesting alternative for perfectionists.
Requires Android 4.1 or higher
