The $12.9B fitness app market is dominated by subscription-first apps that users increasingly describe as overpriced for generic content. Fitbod, JEFIT, and Freeletics all charge $30-70/yr for cloud-based AI that delivers repetitive workouts. Apple's Foundation Models framework enables truly personalized workout generation on-device at zero infrastructure cost — creating the first real alternative to subscription fitness apps.
