: It seems like it's only been a few weeks since developer Marco Arment last released a big upgrade to the . Wait. ! But there are some important changes here--so that users who want to swipe "pages" of a story (instead of scrolling down) can do so faster; he has also given them the option of using iBooks-style page animations. The app now includes a draggable dot bar to replace the scrollbar when it's in that pagination mode. Other changes include a new two-finger swipe gesture to close articles, improved sharing functions, and a few bug fixes.

: There are any number of translation applications that will take your written text and convert it to another language. The $1 app for iPhone works a little differently: Speak into it, and you'll hear your sentence played back to you--in any of 31 different languages. Using the app's voice-recognition features, you can look up foreign words and their definitions, then share that information via mail, text, or Twitter. Users who feel silly shouting Italian phrases into their phone can also type the words they want translated. Cool as it is, the developers warn that the app is not a replacement for a professional translator--"yet." Ciao!

: In space, no one can hear you blow stuff up. That's not really a problem in the $7 for iPhone and iPad. In the game, you play Kal Wardin, a character who returns to Earth after 10 years in exile--but believe it or not, new challenges arise that require Kal to once again save mankind. You can play in a ten-level campaign, or you can join 12 multiplayer battles in six multiplayer modes, all while running, shooting, driving, and flying.

: Twitpic's been around almost as long as Twitter itself; it's one of the most-used services for linking and displaying pictures on the social network.

You can do modest edits like cropping, adjusting for brightness, changing the orientation, and even adding some Instagram-style effects. You will literally see your iPhone pictures in a whole new light.
