While we can generally figure out how to operate most new apps with little instruction, Peek Calendar required a trip to the tutorial before we got started — one of several we made during the course of reviewing the app. It's not so much that Peek is overloaded with powerful features or intricate gestures, but rather it rarely led us in any logical direction. Peek Calendar pushes the iOS 7 human interface guidelines to their limits with its ridiculously minimal, gesture-heavy approach, but while it tries to limit the amount of time you spend interacting with your calendar, its unique concept is ultimately too smart for its own good.
Updating a beloved app for iOS 7 is no easy task. Simply tweaking the interface to match Apple's lighter, cleaner style can affect the user experience in unexpected ways, but a full-on overhaul can bring its share of problems too, as features are squeezed out in the name of simplicity. Released as a new standalone app, Fantastical 2 has neither of these problems. With an effortless redesign that refines everything we love about the original version, the calendar app retains its spot at the head of the class.
