Willow Pro is a lifestyle application designed to help users test and implement protocols aimed at enhancing health, wellness, and performance. The app utilizes custom variables known as qualities and actions within its protocols. Qualities represent areas for improvement, while actions are the daily routines that contribute to achieving desired outcomes.

The protocol page serves as a hub for users to manage and customize their protocols. It allows users to track recent inputs, log qualities and actions manually, and make adjustments as needed. The insights page provides visual representations of progress through charts and rankings, highlighting the impact of different actions on qualities. Users can also jot down notes and gather ideas for refining their protocols for better results.
