In the past months, I’ve taken a look at different calendar applications for the iPhone and iPad that aim at bringing more functionalities (either through particular interface approaches, extended Google Calendar support, or other features) to a device’s built-in calendar software from Apple. The iOS calendar app, a tiny version of iCal for the desktop, is fast and elegant and works just fine for most users, but sometimes you want or need more from a mobile calendar or agenda. For instance, the possibility to have more views available (rather than the List, Day and Month ones designed by Apple) or “do more” with events and reminders. And while I know most of MacStories readers are huge fans of Calvetica and Cloud Calendar for the iPhone and iPad, respectively, I’m pretty sure some of you have been looking for a slightly more “powerful” or, dare I say, “geeky” alternative to Calendar.app. If so, meet Week Calendar.

The name says it all: Week Calendar’s biggest feature is the weekly view that’s the focus of the entire experience and undoubtedly something that Apple’s calendar app really lacks. In the app’s weekly view you can pinch & zoom vertically or horizontally to show / hide hours and days, double-tap to focus on a specific event or rotate to landscape mode to gain an even broader view. Tapping on the top toolbar allows you to select a date to jump to, whilst selecting an event opens a desktop-like popup with related information. Tap on the popup, and you get to another screen with all the details you’ve entered and buttons to share, print (that’s right, AirPrint) or create a template off the event itself. You can edit an event at any time, and even display the assigned location on a map. Something that I really like about Week Calendar (well, weekly view aside): you can link contacts from the Address Book to an event. Like I said, everything’s pretty full-featured to offer a wide array of options and choices.

“Choices” seems to be a prerogative of Week Calendar: from the main screen, an iPad-like popover lets you switch between 7 different views: List + Search, Day, Week, Month, Year, Agenda, and Today. The “Go to a Day” shortcut lets you manually enter a date to open. Switching between sections and views felt fast and highly responsive to me, although I have to say I’ve only configured the app with two calendars: my personal one, and US Holidays. The app comes with this kind of optional, built-in subscriptions that you can activate from the Settings. Speaking of which, there’s a lot of stuff to choose from in there: from Time Zone support and “Week starts at” to an auto-coloring system for events with a specific title, you can stay assured the option you’re looking for has been implemented in Week Calendar. I can see how many will prefer the simplicity of an app like Calvetica, but sometimes an application for “nerds & power users” is more than welcome. Other features of Week Calendar that impressed me for the quality of the implementation were fullscreen support (you can activate it with a single / double tap and choose what UI elements to hide), possibility to cut and drag & drop events in any view for easy re-arrangement and TextExpander integration.

Week Calendar is an app that needs to be used for weeks – even months – to be fully appreciated. There’s so much stuff to play with, configure and customize it’s not really easy to fit everything into a single article – plus, I believe all these options have the added value of turning the app into a completely different experience depending on how you use calendars. So, head over the App Store now and buy Week Calendar 3.0 – at $1.99 it’s possibly the most “serious” calendar app for iPhone I’ve seen so far. Read more
