In addition to day, week and agenda views that have improved aesthetics and usability features compared to the stock app, there are also two new views that combine agenda and month views in interesting ways.

In the older versions of Today Calendar, the icon would have the current days date, sadly this was removed with the redesign of the app.
Con App crashes too often
