Based on the brand’s tagline “That Easy”, the app was created to make user’s life easier by allowing them to get different kinds of products to the place they are located.

Oxxo was just selling through its physical convenience stores, so the great opportunity to grow its business, become digital and do its own deliveries showed up. The project incorporated machine learning and business intelligence board tasks.

Design rationale:

Live your best moments without interruptions.

Considering the best moments of life as something positive, I wanted to design a happy app based on mindfulness, flow and meaning. A design that you feel in your body. As the user of the design, there is the feeling that you are being paid attention to. The visual elements embrace you to keep going, it allows you to immerse in the task while losing track of time. I wanted to avoid any friction between the user and the design in order to facilitate the process.


Happy Colombian living and
