The calories you burn with everyday movement are tracked directly in MyFitnessPal. So workout while you work and make every step count! The Lumo Back Sensor and App deliver real-time feedback, empowering you to make small, incremental changes that have a significant impact on your health. If you slouch with your lower back, lean forward, lean backwards, or shift your weight to one side, Lumo Back will gently vibrate so you can learn to correct your stance. The app keeps track of your daily metrics and lets you view your Posture Score, sit time, stand ups, steps, and sleep time and position.
