User Experience Enhancement in Strength Training Apps: Design Guidelines for Augmenting Continuance Intention

User Experience Enhancement in Strength Training Apps: Design Guidelines for Augmenting Continuance Intention
David Halbhuber

The number of users of mobile applications in the field of health and fitness management as well as the number of people attending fitness facilities in Germany is increasing every year[1,2]. More and more people are using mobile applications to document their sporting activities, training progress and fitness goals. A prerequisite for achieving these goals is, for example, comprehensive support from trainers, be it independent personal trainers or personnel in gyms. A large part of the supervision in strength training takes place via training monitoring apps. While their development and UI designs have been researched and developed, they have not been examined in detail for the aspect of UI design decisions that promote continuous use of the app by exercisers.

Zielsetzung der Arbeit

The aim of this work is to conceptualize a set of design guidelines for mobile app developers that increase user continuance intention.
