Peek Is a Colorful, Gesture-Based Calendar
iPhone: By their nature, calendar apps tend to be a little complicated and busy. Peek is an app that simplifies your calendar down to just the most essential details and uses a completely gesture-based interface so buttons don't get in the way.
Peek is a bit like Clear in that it's main aim is to provide a decidedly simple design over a large set of features. Instead of a bunch of buttons, you'll use gestures to get around in Peek. This take a while to get used to because not everything is intuitive. Tapping and holding a day adds an event, a swipe views the length and location, an awkward "shading" gesture reveals the time, and everything else is done with pulls, swipes, and presses. It takes a while to get used to the control scheme, but once you get it, Peek works well.
