Great!!! This app helped me to learn algebra from zero. Although, it would be perfect if the links worked. Aunque hablo español el lenguaje es sencillo y fácil de entender con nivel intermedio. I thank developers for the effort they have made creating this app.

Love these learning resources from openstax. I've used some of the PDF versions b4, but this app version is excellent. With such knowledge and learning at one's fingertips (and for free) this app is easily a 5 star app. Highly recommended.

i like this app. however, there is just one thing you need to do and that is add page markers. when you leave the app you need to remember where you left off. just add a page marker and i would give you a 5.
