Briefly: A look at the Macworld App Store announcements

While no one app demonstrated at this week's Macworld is dominating coverage, several do offer VoIP calling, TV watching, and more. Here's a brief rundown of some of those offerings, including SlingPlayer, Truphone, Fring, StarPlayr, and Eye-Fi.



SlingPlayer Mobile for iPhone



SlingPlayer Mobile for iPhone isÂ*slated for releaseÂ*by March.Â* The app will enable live television from a home TV setup, streaming from a Slingbox over WiFi or 3G.Â* A built-in remote control will let you change channels and mange your DVR.



"SlingPlayer Mobile is ideally suited for the iPhone's large touch screen display and I know iPhone users are eagerly anticipating the application's availability," said Sling Media chief executive Blake Krikorian.Â* "...Sling Media is committed to delivering great solutions for Mac users."



The price has not yet been announced.Â*Â*(SlingPlayer Mobile for Windows Mobile, Palm OS, BlackBerry and Symbian have cost $29.95.)Â*The app will also work on the iPod touch. Â*Sling is targeting late first quarter to send the app to Apple for approval.











Truphone



TruphoneÂ*will now have the ability to make and receive Skype calls and instant messages. Â*As long as you're near WiFi, it can effectively turn the iPod touch into a phone, with a second generation model and compatible microphone required. Â*Users can bring their MSN Messenger, Yahoo! Messenger, and Google Talk contacts to the calling party as well.







Calls are free over WiFi. Â*Calls to other mobile phones and landlines are billed at low rates, while calls - even international ones - between two Truphone users are free. Â*Pending Apple approval, the updated versions of Truphone for bothÂ*iPhoneÂ*andÂ*iPod touchÂ*should appear in the App Store as free downloads next week.



Fring



Aimed at a similar consumer as Truphone, Fring for iPhone serves as a unified home for all of your contacts across multiple chat clients. Â*While it's not the first app to do so, its addition of VoIP gives it a heftier feature set than some of its competitors. Â*







Fring supports Skype, MSN Messenger, ICQ, Twitter, Google Talk, Yahoo Messenger, and AIM. Â*Plus, it has SIP support for a number of VoIP providers. Â*If your client of choice isn't supported, the developers have been known to release updates in response to customer feedback.



Fring requires a WiFi signal to make calls; it will not work over Edge or 3G. Â*It's available now, also as aÂ*free download, at the App Store.



uSirius StarPlayr



Already in beta,Â*uSirius StarPlayrÂ*lets you listen to satellite radio on your iPhone, and unlike some of its competitors, you don't need another computer running to accomplish that goal. Fire up the app to enjoy streaming Sirius-XM satellite radio, provided you have a paid subscription, of course.



Album art for whatever's playing is displayed prominently in the middle of the screen, with a button beside to call up the lyrics and another that sends you off to Amazon or iTunes if you want to purchase the song. The app is expected to land in the App Store sometime this month.







When streaming over cellular, the quality is capped at a lower bitrate. As you might expect, listening over WiFi gives you full quality.



Eye-Fi



Eye-Fi wireless cards already enableÂ*wireless transferÂ*of photos from a digital camera to your computer or to any of 25 online photo sharing sites. Â*At Macworld this week, Eye-Fi is previewing a new iPhone appÂ*to bring the popular touchscreen device into the loop. Â*







Still in development, the app will let Eye-Fi card owners send photos taken on an iPhone directly to their computer and to the Web. Â*Once released in the App Store it will be a free download. Â*If you're attending Macworld, you can see how it works at booth #3315 in the North Hall, according to the company.
