I really love this app! I've always appreciated having the answers to odd-numbered questions in the back of the book, but it didn’t really help me understand what I did wrong or what I'm supposed to do. This app gave me that little extra boost I needed!
Other reviews mention blurry answers, but I haven’t experienced that yet. I'd say it’s worth a download anyway.
If your math class uses a Larson textbook, this app will most likely be more helpful than any website or forum or calculator out there.
That being said, they sometimes skip steps, and of course, it only has half the problems. It's not a super pretty UI, but you can get from section to section and from problem to problem within a couple seconds. To me, these “problems” are not bad enough to take off a star.
