Here are two different potential user personas. One is interested in browsing and the other one is trying to collect. These personas created a guide for me when making the flows and certain tasks.
FLOW #1 & WIREFRAMES
The first flow is for Sally, the first persona. The main goal for this flow is browsing for books to eventually purchase. This flow shows different ways in which you can find books using Must.
FLOW #2 & WIREFRAMES
The second flow is for John, the second persona. The main goal for this flow is adding read books quickly and browsing insights about your progress. This flow shows quick ways to add books and ways to see how fast you're reading a book.
I tested 5 people on the two flows and it was overall successful. All tasks were completed in one or two tries, however, there were some comments that stood out through the testing. Here are some of the changes I did according to the comments. I also did smaller bug fixes like typos and icon inconsistencies.
