Screen Replay is a high-quality, clean, and easy to use screen/microphone recorder for Mac OS X. It takes advantage of all the available resolution of your screen, even if you have a retina display or 4K display. It can record any length video with no limitations or watermark. Screen Replay is the only recorder available from the Mac App Store that has all features available for free, immediately after you download and install.
With an extremely simple user interface, Screen Replay is one of the easiest to use of all screen recorders. Screen Replay will record audio from the built-in microphone as well as an external mic, and will capture video in full resolution. ScreenReplay will also capture system audio as long as headphones, earphones, or a headset is not present.
