Comparison with Other Tools

Flex Fitness App vs Freeletics:
Freeletics also offers AI workouts, but Flex has a simpler UI and better personalization at a lower price point.

Fitbod is gym-oriented with a focus on weight training. Flex is more bodyweight-based and better for home users.

Flex Fitness App vs Centr (by Chris Hemsworth):
Centr includes wellness and nutrition content, while Flex keeps the focus on fast, effective workouts.

Flex Fitness App vs Nike Training Club:
Nike’s app offers high-quality workouts but lacks the adaptive AI feedback that Flex delivers after every session.
