“About a year ago I became homeless and had to withdraw from class leaving me unable to receive financial aid. Being a single mom of two children I couldn’t possibly afford a $200 book, but your book made it possible for me to go back to school without the stress of “how will I afford it.” Thank you! I really hope openstax grows, because you guys are providing a way for me and many others to get a better education so we could better our lives.

I am appreciative of the content and ability to access the material for free by only setting up a free user account. My professor has chosen OpenStax as our only textbook. I do agree that there should be some quality of life updates such as auto screen rotation and pinch to zoom. I use a tablet and am older than what I suspect the normal student is. The ability to adjust the font size is important to me. The autorotation is a convenience that seems to be ubiquitous in all other reading apps. Thx

Considering students seem to be constantly on an electronic device, I was happy to have found an app that enabled them to access their textbook at any time (and available for both android and iOS). However, students have voiced a great deal of frustration about, and disappointment in, not having the options to highlight, add notes, and bookmark pages, which has reduced the desire to use the app.

Seems great from first impression. I don't feel the need for videos though. Wouldn't mind subscribing if there was an offline feature. Like downloading a section to view offline. I travel around and I'm frequently offline. Another feature that would be cool is a night mode. Like I'm laying down at night in a hotel room and not having a mass of white light shining in my eyes.
