N of 1 Fitness

N of 1 Fitness is a science-backed remote coaching platform built around one simple idea: you are not a generic client, and your program shouldn't be either. Founded by Dr. Bailey Devine — experimental psychologist, Board Certified Behavior Analyst, and certified personal trainer — N of 1 Fitness uses the principles of behavioral science and individualized data collection to build programs that actually fit your life. Not an idealized version of it. This app is your hub for everything coaching-related. Access your fully customized training program, log your workouts, track your progress over time, and stay connected with your coach through in-app messaging. Every program is built specifically for you based on your health history, goals, available equipment, schedule, and lifestyle — then adjusted over time based on how you're actually responding. Whether you're an N of 1 Method client or a Consistency Lab member, this app delivers your programming, tracks your data, and keeps you accountable between check-ins. Features include workout logging, progress photos, in-app messaging, habit tracking, and Apple Watch and HealthKit connectivity for seamless health data integration. N of 1 Fitness is a remote coaching service. This app requires an active coaching subscription and trainer invitation to access.
