In the realm of SDT, autonomy refers to the innate human need for independence and the ability to make choices based on personal preferences and values. Autonomy is a key psychological need that significantly influences human motivation and well-being. When it comes to UX design, addressing users' need for autonomy plays a critical role in creating engaging and satisfying interactions.

Consider how a fitness app may address this need of users:

• Allow users to personalize their workout routines
• Allow users to set their fitness goals
• Allow users to select activities that align with their interests and fitness levels
• Allow users to set their own workout schedule

By incorporating autonomy into this fitness app, users will feel empowered to shape their fitness journey based on their unique needs and preferences. This sense of independence and control enhances the user experience, fostering a stronger sense of commitment to the app and encouraging users to stay engaged in their fitness pursuits.
