App demo: Round the Clock
While Round the Clock seems a bit gimmicky, there are a few nice things besides the presentation of data here. First, there are extra edges to pie wedges to indicate travel times so your schedule can accommodate those. Next, there's a simple swipe movement to change days or weeks or even months on the calendar. Why Apple's Calendar app doesn't do this I'll never know. You can also shake at any time to return to the "Today" view — although in real life I've found shaking an app can lead to unintended consequences (sliding down a bench can indicate a "shake" to the iPhone's peabrain).
Adding data in the app is actually one of the coolest features as the UI has you using sliders and nice, big buttons to enter your info. If you've ever cursed at Apple Calendar app and the crummy way data entry is handled (how many times do I have to forget to save something?), know that Round the Clock does it better. Plus, the way it handles things that happen with regularity is excellent. I guess in Cupertino nothing ever happens on "the last Thursday of every month" but in my world it happens a lot. Round the Clock is the best I've seen at tackling that specific issue.
