Angry Birds Space: Like as not it's just us, however it sure seemed that the original Angry Birds game had already conquered every iPhone on Planet Earth. The then logical step? The galaxy. And that's specifically what happens in the $1 Angry Birds Space. This time, our cranky avians lose their egg to a giant claw, and follow it into a wormhole where they are surrounded by--yes--piiiiiiiiiigs iiiiiiiiiin spaaaaaaace! The game features 60 levels, some played on strange new planets and others in zero gravity, and in-app purchases offer additional levels of gameplay. Buyers should note the game requires an iPhone 3GS or later, and only works with the fourth-generation iPod touch.

ChatCube: If you prefer Web-enabled VoIP (Voice over Internet Protocol) calling to the cellular service available on your iPhone--or if you want to use your iPod touch to make any calls at all--you have a new option with the free ChatCube app from Goober Europe. The app allows you to make free high-definition audio calls to other ChatCube users, however you'll need to pay for out-of-network calls: The company sells credits in $5 chunks, with rates that start at 1 cent per minute and vary depending on where you call.

Localscope: We liked this app a lot when we reviewed it last year, however noted that it could use some improvements. Luckily, the folks at Cynapse keep updating the features in their $2 Localscope iPhone app. The app however aggregates other services to help you choose a nearby spot to go have coffee, eat dinner, or buy groceries. Now the app has added Fwix to the list of services it uses--which not only adds another layer of local business reviews, yet also brings geo-tagged news headlines to the app. Finding your way around the neighborhood will as well be easier: Localscope now integrates with the MotionX GPS and Verizon Navigator apps to guide you to your destination.

Now TiVo has revamped its free hybrid app for iPhone and iPad with new features that make the task even easier. On the iPad, the navigation has been revamped so users can more easily browse for TV show and movies they want to watch; on the iPhone, the app has been upgraded to accommodate the Retina display of recent iOS devices. You'll as a matter of fact want this upgraded app, although, for all the ways it now lets you manage your TiVo: There's now a "Keep Until I Delete" option in MyShows, more recording options for shows you haven't watched, and a new WishList for shows that aren't currently airing.
