Weight loss coaching app



Designed in 2019. I ran a design sprint and designed a weight loss coaching app for Kilo.
During the 5-day design sprint, we tested two prototypes and chose the one that worked better. Then, I designed that app from scratch - starting with the UX and ending with a UI with a design library.

The Challenge

The challenge here was to achieve results in just a couple of months. The client has a couple of different approaches on how to build the app, and I ran a full 5-day design sprint (AJ&Smart way) to pick the two prototypes to test and get feedback. Moreover, It's a difficult task to create an app that forces you to change your habits and works as a marketplace at the same time.
