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.
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.
Apple's solution to that admittedly small glitch adds a bit of cool to Face Time.
Regardless of the device we used--an i Pad 2, i Phone 4, and a 13.3-inch Mac Book Air--Face Time offered some of the most dependable video quality we've seen.
For the i Pod touch and i Pad 2, launching the Face Time application activates the front-facing camera immediately, so your own first-person video takes up the entire screen.
A list of Face Time contacts is transparently overlaid on the right side of the display and allows users to make calls by tapping a contact's name.
Calls made to the i Phone 4 from another i Phone 4 were clear at a glance, but a deeper look revealed that they contained some pixel noise.
The edges of our face looked only slightly less blurry than on video calls made with Skype and Tango, but it was much better than Oovoo, which struggled over Wi-Fi.
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.
