We're seeing a large upsurge recently with more official apps appearing in the Windows Phone Marketplace. This is starting to mirror last June when Microsoft unleashed a torrent of official apps for the fledgling mobile OS and it looks like a similar pattern is starting to build.
Now LinkedIn and Time Magazine each have official apps to their name and we decided to take both for a tour on our trusty Titan II.
LinkedIn, like Facebook, is native to the Windows Phone OS allowing you to post updates and track updates from your colleagues via the People Hub. The official app augments that with a gorgeous Metro inspired design and allows more in depth functionality, including management of messages, search for new potential contacts, sending out invites, managing groups. What's more it also has a moderately configurable Live Tile and push notifications. Overall, a solid offering.
Likewise, Time Magazine has an official app to its name as well. The app is also top quality with fast loading, nicely laid out text, smooth transitions, social sharing, video streaming of stories and photo galleries. That app has a Live Tile (latest image) and push notifications presumably for "breaking" stories.
Oh and we've heard a certain Wall Street Journal official app is right around the corner. You heard it here first.
