Key Business Goals:
To improve engagement and design monetization strategies, I recruited users to use the app for 7-10 days and provide feedback on their overall experience, the usability of specific features, their willingness to pay, the ideal customer profile, and any changes they would make.

Ultimately, I was tasked with redesigning LePal’s mood tracker to prioritize simplicity and emotional clarity. The updated screen allows users to:
