There's nothing wrong with the stock calendar. But this app just looks so pretty. I have Beautiful Widgets and a Digital calendar widget on my homescreen, which look perfect together. Probably the best 3rd party calendar app.

Hands down one of the best calendar app around. I've trialed several different calendar apps, some of which I've even paid for to get the advanced features but Digical beat them all hands down. Digical integrates with ALL of my calendars and make everything easy to see and organize. The widgets are simply beautiful and if you can spare $1/yr, you should get the weather add on as well.
