Flipboard Inc. has updated its free Flipboard app to version 2.0. The web article aggregator now lets users collect and save content into “magazines” that are public by default, but can be made private. A new bookmarklet makes it easier to add items to magazines from your browser, and sharing to Facebook, Twitter, and other social networks is now easier. Personalized recommendations are now available, and search — now in a more prominent position — has been improved.

Repulze ($3), the futuristic racer from Pixelbite, has now been updated with additional features that bring it closer to Sony’s classic Wipeout series. Version 1.0.4, aka “Phase Three,” adds weapons and AI opponents to the game. New challenges, hovercrafts and tracks have also been added. At this point, the weapons are still pretty basic, and the stages don’t have quite the right balance of weapon-racing action, as Repulze continues to feel like a beta version of a finished game. But the graphics and speed continue to improve with every release, and if subsequent updates evolve the weapon systems further, Pixelbite might just have an excellent game on its hands.
Warner Bros.’ popular Scribblenauts ($1) game has updated to version 3.0. New additions include a beach playground, free lifeguard avatar, and most notably, additional levels through an update of the game’s World Pass. While the additional levels didn’t initially appear for us right after the game was updated, Warner appears to have flipped a switch of some sort to enable them, adding extra worlds that are presented in groups of ten at a time. The game’s World Pass ($1) in-app purchase features all current and future world expansions.

The Weather Channel Interactive has updated The Weather Channel (free) app to version 5.3. Now boasting a new design, the app allows faster navigation to live radar, maps, videos, and pollen levels. A new tab on your Now screen offers specifics about precipitation — the Expect Rain tab lets users now if snow, rain or thunderstorms will start or change in the next six hours. Severe weather alerts and 15-minute forecasts have also seen improvements.
