Colette is at Tufts University and has diabetes mellitus type I. She has difficulty finding products with a minimal glycemic index.

“I would like an app that registers and carb counts the products in order to rank what is available in each store per product category.”

0. User research – shopping with Colette

1. Colette’s persona
2. Colette’s healthy meal diary
3. Colette’s daily journey with GI

Through the mapping of Colette’s daily journey, I identified 4 different main functions for her and other similar app users, namely the documentation, searching, calculation and sharing.

4. Compare with peer applications

The current applications are mostly designed as a static dictionary, which is basically another format of a website. They lack of real-time interaction, do not have personalized information tracking function, and do not satisfy Colette’s sharing and education need.
