Fantastical is one of my must have apps for the Mac and it's now available on the iPhone. The iOS Calendar has always been "fine" but nothing to be excited about. Fantastical for iPhone has quickly replaced the Calendar.app on my home screen. The interface is gorgeous, and with their "DayTicker" view you can at a glance see your appointments for the day and how busy the day will be. Best of all, Fantastical's hallmark feature of creating events using natural language is finally available on my phone. Fantastical for iPhone is currently on sale 50% off for $1.99.
