I want to tell you about an amazing tool called QuickCast. QuickCast is designed to be lightweight, free and simple to use. It allows you to make 3 min screen casts to help teach and explain anything you do on your Mac.
Once installed, it's easy to record your 3 minute screen cast to share with the world. Simply select the QuickCast logo in your toolbar and then click record. You'll get a 5 second count-in and then it's showtime. While you record keep an eye on the QuickCast icon, it will indicate how much time you have left.
Once you're happy with your QuickCast, you'll be prompted to publish and share it with the world. Every QuickCast you make gets it's own unique URL and embed code to use on your own site. Your published links are also easily accessible from the QuickCast status bar icon.
This app is amazing for helping you quickly walk someone through both simple and complex tasks on your Mac. Although it is currently only available on OSX the developer says that it is going to be available soon for Windows. So check out QuickCast and let us know what you think. You can download QuickCast from the Mac App Store.
