Fed up with your stock Android calendar? Perhaps your HTC Android calendar? You may want to give Business Calendar a shot, particularly today. Normally $4.99, today Business Calendar is the free app of the day through the Amazon App Store. Business Calendar gives you a great overview of your schedule, either by day, week, or month. By default this is set to month, but simply by pressing a day, it shows a little drop down with detailed information, allowing you to see everything you want without having to go back and forth between different views. If you’re looking to make your calendar a bit more productive, I highly recommend checking out this app.
