"It doesn’t take more than a cursory exploration of the application Explain Everything for the iPad, to find out that it is an incredibly useful and versatile app. So what is Explain Everything, exactly and what does it do? Well the answer to that question is in the name of the application itself. You can use the app to explain and share tutorial videos, collaborate with others and develop ideas and you can also use it to do live interactive presentations, using an iPad in the classroom."
