e. Summary of what prospective users liked and disliked.
Users generally like the clean and simple appearance of the app. One user had difficulty changing the quantity of items because the number entry field was right justified, making it hard to click in the right spot to delete the existing value. I fixed this by making the field left justified.
Users also wanted more clear visuals and immediate feedback. When changing the quantity of an item, the input options push the item information off the top of the screen, which was somewhat disorienting. In addition, on adding an item to the cart, a user expected to be taken to the cart, rather than back to the catalogue. Despite these issues, users found the app performed as expected and was easy to use.
