Method used: The usability study was conducted with a use of a mobile eye-tracking device. That method was chosen due to a necessity for exact users’ gaze tracking. This was the only means of collecting such special sort of data which could not be described by supervisors in any other way.

Problem finding: During the user sessions there were several critical usability problems identified accompanied with lots of smaller issues which frustrated app users or simply interrupted proper functioning of the app.

Recommending solution: I formulated recommendation which helped improve the overall user experience but also raised the conversion of the app.

Design solutions: I added new global bottom navigation to the app (a left picture below). The categories and subcategories pages were redesigned as well as the pictures of product categories were changed (a right picture below). Product pages are the most converting pages in the e-commerce, so I proposee a solution which makes it easier to switch the units and add the products to the basket. Some minor improvements swere proposed to the checkout especially booking time slot tab and the way of choosing the delivery method.
