Tapping iOS video recording APIs, xRec by developer Akın Öğünç lets you easily capture contents of your iDevice’s screen, without having to jailbreak or cheat by hooking up your device to a computer to use a desktop screen capture software instead…
In order to record video on your iPhone’s screen, all what you have to do is opening the app choose Settings and set your desired orientation.
You’ll have to wait a bit until the encoding process finishes, which can take anywhere from seconds to minutes, depending on the length of your video capture session and the speed of your device. The speedier the device, the smoother the video.
xRec is compatible with the iPhone 3GS/4/4S/5 and third-gen iPod touch or later running iOS 5.0 and up. The 4.4MB download is on the App Store and will run you $1.99.
