"If you are interested in creating video lessons using your iPad you’ll definitely want to check out Knowmia Teach Pro. This powerful tool lets users make their own recordings using a virtual whiteboard to annotate images, draw pictures and add text to the screen. In addition to capturing everything you write on the screen, Knowmia records your voice and a video of you speaking into the camera. There are tons of tools for you to explore within the app."
