Customer Reviews

Unorganized and rambling.

It's a collection of rambling and unedited recordings by, I'm guessing, the creator of the site. It's a wonderful concept and having audio lessons to listen to while working or doing other things is invaluable but it would be better if you could find some actual professors or educators in each field to organize the content in a way that was actually comprehend-able and create audio recordings that follow that content. The doodles are difficult to see. And this designer really really needs an editor to make it sound less rambling.
It's a start. I'm glad it's free for now.


I honestly have never learned so quickly from any other videos. Things are explained the simplest way, the videos are set up well, and there are so many videos that it seems impossible to search a subject and not find one.

Thank you so much for this app. I'm struggling to learn math right now and these videos help so much. If you are struggling as well, GET THIS APP!

It helps

I was struggling because I went into a different district and my previous school and my new school stopped at different lessons in math so when I went to my new school there was a big chunk of information missing and this app helped me fill in the missing part in my brain thanks to this app I am getting better grades.
