This thesis explores the application of motivation theories in the development of a gym workout app designed to enhance user adherence and engagement. Grounded in behavioural psychology, the app incorporates key motivational frameworks to foster intrinsic and extrinsic motivation. A central feature of the app is the integration of an accountability partner, either digital or human, to encourage users to stay consistent with their fitness routines.
A key focus of this thesis is the interface design and user experience (UX), ensuring that the app is both engaging and effective in sustaining long-term fitness habits. This project will explore how elements like progress tracking, challenge systems, and interactive accountability features impact user motivation and adherence. To validate the app’s design and effectiveness, a small usability study will be conducted with a group of potential users with a hi-definition prototype.
