INJOI Fitness faces several challenges, including maintaining user engagement and retention with home-based workouts, as motivation can wane without in-person interaction or community support. The highly competitive fitness app market also requires constant innovation to attract and retain users. Personalizing fitness programs to suit individual goals, fitness levels, and health conditions can be challenging, as each user’s needs vary. Additionally, ensuring smooth functionality across all devices and maintaining accessibility for users with varying technical skills and internet connections remains a hurdle. Lastly, integrating sustainable practices across all aspects of the app, from content creation to marketing, requires ongoing effort and resources.
