Visualization of Public Stool-Health Data

Overview
The Danone App has accumulated check-in data from tens of thousands of users, raising a key question: Can we identify user habits from this data to support feature optimization and product promotion?

We observed that the previously overlooked “stool condition” check-in module was used much more frequently than expected. In response, we conducted a feature-level analysis of this stool condition check-in data, visualized our findings, and used these insights to redesign the stool condition check-in feature.

Background ResearchThe French research institute IFOP conducted a survey among employees on bowel habits. The results show that bowel-related embarrassment is highly prevalent.







Data Analysis & VisualizationAnalysis of 5w+ user data from the Danone app reveals that people monitor their stool health privately, but struggle to maintain long-term consistency.










Based on stool check-in data, we conducted an analysis and visualized the results, revealing the following patterns:
  • Users with worse stool conditions tend to check in less frequently.
  • Users with more favorable stool conditions generally check in more frequently.
  • Users with more favorable stool conditions also tend to complete more probiotic check-ins.









Redesign
Building on the insights uncovered from stool check-in data, we redesigned this feature in the Danone app and carried out iterative testing to increase check-in participation and probiotic sales.
