It brings workout planning, training logs, gym accountability, fitness motivation, community, education, and rewards into one place so you can build muscle and stay consistent. Some features require an account, internet connection, foreground location access, or paid membership. Accountability requires a fresh precise foreground location when the form opens and again before either a Gym or Home Workout check-in is submitted. Gym check-ins use this location to find nearby gyms and verify proximity to the selected gym. Home Workout check-ins use it only for live submission validation; device and gym coordinates are not stored for Home Workout. MASS Monster does not collect location in the background.
