We created an interactive low-fidelity prototype of our app using Marvel.
Usability testing revealed some flaws that we suspected might be confusing or problematic to users. In the first iteration, the hamburger menu icon was located on the right of the screen, yet in our wireframe the expandable menu extended from the left of the screen. Testers noted that this was odd, as they expected it to extend from the menu icon itself rather than the opposite side of the screen. We also noted a few gaps in logic during the test, such as the lack of a pop-up keyboard during one portion of the payment process.
Overall, however, comments from testers demonstrated they felt our app was easy to use and highly functional in their daily lives.
