Still, the option to make video calls, even of slightly poorer quality, wouldn't hurt.Google Chat, Fring, oo Voo, Skype, and Tango each work over 3G and 4G data networks as well as Wi-Fi.For instance, the small thumbnail of the video feed can be dragged or flicked from one corner to another with your finger, and when your caller switches from the back camera to the front one or vice versa, the video feed actually revolves around to indicate to the other caller what's happening.When this action happens in each of the other video chat applications, the video feed simply freezes for a split second before it reappears jarringly with different video.Calls made from the Mac Book Air to the i Phone 4 and the i Pad 2 video looked clean, but the edges were still fuzzy.The worst picture quality we noticed was while calling an i Pad 2 from an i Phone 4.Still, Face Time delivered solid video connections, and the audio was the best of any app we tested for this roundup.There was almost no latency, and the sound quality was so clear we hardly ever missed a word.
Fring allows users to make up to four video calls at once, and oo Voo Mobile can host up to six audio calls with a single, shared video feed.
While it's only available to i Pad, i Phone, and Mac users, Apple's Face Time video chat app has an intuitive interface and excellent quality.
However, other players in the video chat market such as Fring, Oovoo, Skype, and Tango can make face-to-face calls to Android and Apple devices, and some can conduct multi-party video calls with four or more people.
The latest i Phone captures video that's fine for another i Phone's 3.5-inch display.
The i Pad 2's 9.7-inch display must scale up video from the i Phone's camera, and the result is scratchy, pixelated video on the tablets's screen.
