I’m a teacher and have been using the free version for years. It works great with the Apple pencil. This pro version has everything I wanted. Some might not like you can’t type on it, but I think the simplicity of the app is what makes it so good. No other similar app from those big companies provide the same feeling of freedom from writing on a real whiteboard as this one. At work, I AirPlay my iPad to the classroom TV and students enjoy how I can visually explain grammar this way and also share captures with them on Google Classroom.
