A screencast is a digital movie in which the setting is partly or wholly a computer screen, and in which audio narration describes the on-screen action. It's not a new idea.
Aside from recording screen videos, this app also has a built-in gallery where you can watch, delete or rename the video files that you recorded. The app doesnât work on the Samsung Galaxy Nexus and Tegra Android devices. Screencast also lets you take screenshots on your device.
