“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.

Easy to Navigate!

The textbook is organized nicely into sections that make it easy to find what you need. I like the hyperlinks that take you to exactly what it is referring to, which is convenient to have and something you can’t do as quickly with hard copy textbooks. It’s also nice to have the key summaries as a quick reference when studying. However, there isn’t always an answer key to the review questions.

The videos for each section and study guides to follow along with are a great addition. However, I would make it more obvious that there is a “Check Your Understanding,” maybe placed under a folder along with the videos rather than placing it in the 3 dots button next to each video.

Decent, could improve

I downloaded this app to read my school textbooks while I work and there’s a few things that I wish they had. I wish that I didn’t have to go find my specific text every time I reopened the app. I would love to be able to bookmark and save the book in my account so that I may go back and find my place. Another great feature on my other reading apps I wish this one had is a speaker. Someone who reads aloud to you so that you may multitask. I like to listen to my textbook when I’m at work and I can put my headphones on when I’m free to listen and work and the same time. A highlighter! I like to highlight key terms and sentences that I find important but the app doesn’t allow that. I would give this an average score of 3 stars because it could be better and it runs a little slowly.

Great App!!

Love how access to the textbooks is free and everything is divided with their hyperlinks/indexes making it easy to navigate. I didn’t even need to make an account. It has almost all the textbooks for the courses I need plus summaries and reviews. Definitely considering subscribing so I can get access to the guides and videos on certain topics within my courses. Did get a lot of notifications/pop-ups asking if I wanted to pay for video help, but other than that it was great. Wish I knew this app existed earlier, it would’ve saved me time and money.
