Amazon Halo is a lifestyle app that provides you with personalized data and insights to help you build healthier habits for life. This free app requires a Halo device and offers an ever-growing library of premium and on-demand workouts, daily meditations, nutrition, and sleep support.

The app's key features include the ability to analyze your sleep patterns, track your nutrition with a tailored weekly menu that can be synced with your grocery list, and browse hundreds of nutritious recipes. Additionally, Halo uses your smartphone's camera to accurately measure your mobility, stability, posture, and body composition, which is nearly twice as accurate as leading at-home smart scales.

Halo also measures the intensity of your activity, tracks your steps and sedentary time, and provides a custom set of corrective exercises to help you improve over time. Moreover, the app's tone of voice analysis analyzes the positivity and energy of your voice to help you learn how you may sound to others.
