Every week, our staff will handpick an app from the past seven days that we believe is a must-download for your iPhone or iPad. These apps will always be from various categories, but they are chosen because our own staff members love it and have been using them daily. So here are this week’s picks! Enjoy!

NBC Olympics Live Extra

Get ready for the London Olympics events this year with our App of the Week pick!

With the 2012 Olympics coming up (the event runs from July 27 to Aug. 12), it’s never been a better time to get ready for the games. Now you can prepare your iDevice with the NBC Olympics Live Extra app. Please keep in mind that this app does require an active satellite or cable television subscription to stream the live events.

The Olympics, which are taking place in London this year, will run a total of about 3,500 hours. All of these hours of the games will be available for your enjoyment right from the app. You will have access to stream all of the games and events, and you will even get alternative camera options (never miss anything!) and even replays.

Since the games won’t start until next week, grabbing the app now will get you Pre-Game footage. What’s included? You’ll get video-on-demand previews of the London Olympics and you can even relive moments from the Beijing Olympics. A schedule is included so you can make sure what’s going to be happening and even set up some event reminders for yourself to make sure you don’t miss out on the action.

During the games, you’ll get access to live events, full event replays, channels, Gold Zone, alternate camera views, push notifications for upcoming events, and even DVR capabilities.

If you have a valid subscription to satellite or cable and are interested in keeping up with the London Olympics, then there isn’t a better option than this app!

Honorable Mention

Voodoo Skies Normal or Not?

Get a unique outlook on the weather with Voodoo Skies Normal or Not?

Yes, I know that we just had another weather app for the Honorable Mention last week, but this one is also pretty good and best of all, free! Voodoo Skies Normal or Not takes a different approach to the weather, but it also does it in a clean and straightforward interface.

Now, what do I mean by different approach? VSNoN provides a historical perspective on the weather at your current location. The app features an extensive database that contains millions of various weather observations made from thousands of weather sources all over the globe — now that’s a lot of data!

VSNoN will compare the current forecast, including the high and low for the day, with previous weather data for the same day. Despite how undemanding the app is, there are still multiple views — you can swipe left to clearly see the difference between the information of the present day and tomorrow, or you can swipe up and down to reveal rainfall data.

This is definitely a unique weather app that should be given a chance, even if you already have other apps for the job. It’s a nice complement no matter what you’re using, and that’s why it’s becoming a little staff favorite around here. Check it out for yourself, especially since it’s free!
