Justin.TV is the website that lets users broadcast, watch and share live video feeds. The easiest configuration simply uses the camera built into your laptop. Other setups, of course, can be more elaborate.
The App takes many of the features of the website and puts them in the palm of your hand‚Ä¶literally.
The App is streamlined for iOS, but doesn't add universal compatibility. That means it looks like crap on an iPad. Maybe they will add that one day (heck, if that Camera-equipped iPad comes around sometime soon, that's their chance).
Even on an iPhone 3G, (running 4.1) the App is quick and responsive. It launches fast, and feels much better than we would have expected. It even feels better than Apple's stock YouTube app at this point (Which by the way, needs a serious update).
You can check out various videos under several different categories
The streaming over wifi is wonderful. There are a few hiccups here and there, but you can comfortably watch and listen in on a video stream while you comment and nothing seems to choke, even on the wimpy old phone we tested it on.
You can share channels via email or follow something you like
As far as connecting over the 3G network, things work well with a good stream. In fact, we watched some Tech News Today and the video ran flawlessly. We were able to watch the stream with very minor slowdown and hiccups. It wasn't as great as wifi, but it got us by. There were noticeable dips in audio quality when the stream started to choke up. However, it was still very viewable. The bad news? Man it left our poor little 3G too warm for comfort. The thing felt like it had been sitting in a hot car for a few hours.
The App has improved vastly over the past few releases, with features being added here and there that improved its potential. Six months ago, we would have told you the App was a waste of the 30 seconds it takes to download it, but it's finally evolving into something worth checking out.
If Justin.TV is your thing, this App may be for you. We can't personally see ourselves making much use of the App unless it gets scaled up to fit the iPad. Though using it over 3G may ok for travel.
With version 2.0 comes the ability to broadcast your own video via your device. This may not be very useful at home or at a hotel over wifi where you likely have a laptop. However, it is possible to do. The real kicker is the ability to broadcast over 3G. This sounds pretty cool, but we think we are more interested in the idea of a quick video upload since the iPhone can do that anyway. Though it's fairly well-designed at this point, it's not for us.
Either way, it's a free App, so we don't expect it to be a revelation in mobile broadcasting.
