I fell in love with Fantastical for OS X a few years back when it was released and recommend it to anyone who will listen to me and is in need of a better Calendaring application than iCal/Calendar.app. This morning, Flexibits released Fantastical for iPhone. I've bought it already and can heartily recommend it as similarly awesome as the OS X version is. It has now become my default calendaring app for my phone. My only wish was that it was universal for the iPad as well, but knowing Flexibits, they're working on either a universal version now or a dedicated iPad-only version. Make your life better, and get this app.
