Knowmia "Teach" app

I have been using the "Educreations" virtual recording whiteboard app this semester for extra help videos in my Basic Musicianship class.  The students really like the format and ease of use.  Educreations can also be exported and linked to your D2L or website.  I have been playing around with the Knowmia "Teach" app that is much more complex, but states: "Note that Knowmia Teach is a free tool for teachers who choose to participate in the Knowmia community. You cannot export the lessons to other platforms or websites."  I'm not sure how I feel about that.  Here are is a description and features list:

Knowmia Teach is a new free lesson planning and recording tool for teachers. It helps you create short video lessons on any subject and publish them on Knowmia.com so your students and the public can find them. Knowmia Teach makes it easy to bring in visual aids from multiple sources, organize them in steps (like slides in a presentation) and use your own voice and fingers to bring your lesson to life. You can design each step in the lesson, record illustrations as you draw them, and create sophisticated animation sequences with a simple stroke of a finger. We also give you the ability to describe your lesson in a way that makes it simple for any student who is interested in the subject to find your video. 


Main features include:
★ Build your lesson out of smaller steps (like slides) so it's easy to manage and organize your lesson
★ Create each step of your lesson on a separate whiteboard so you can seamlessly introduce new concepts
★ Record everything that you do on the whiteboard as well as your voice and video to create the lesson step-by-step
★ Use the shape tool to quickly draw common shapes
★ Type text with any font/size directly on the whiteboard
★ Import images, graphics or video clips from the iPad's media library and built-in camera - or paste in any image of your own
★ Draw freely with multiple pen widths and a highlighter mode
★ Use the pointer tool to attract attention to anything on the whiteboard while recording it
★ Publish the complete lesson to Knowmia.com with a touch of a button
