NOOA is a smart health and fitness companion app designed to work seamlessly with compatible wearable devices, helping you better understand your daily activities and lifestyle habits. The app provides insights into your daily activity, sleep patterns, exercise performance, and other wellness-related metrics. All data is presented through intuitive dashboards and easy-to-read charts, helping you track your progress and stay motivated. Key Features Activity Tracking Track your daily fitness activities, including: Steps Distance traveled Calories burned Active time Daily activity goals Sleep Tracking Review your sleep patterns and gain insights into your nightly rest, including: Sleep duration Deep sleep Light sleep Sleep trends Wellness Metrics When paired with a compatible wearable device, NOOA displays wellness- related readings collected by the device, including heart rate, blood oxygen, heart rate variability, skin temperature trend, stress level and VO2 Max. Body weight is displayed when measured with a compatible smart scale. Blood oxygen, heart rate variability, skin temperature trend, stress level and VO2 Max are recorded automatically by the wearable device in the background. The app displays and charts these readings, and does not offer on-demand measurement of them. Heart rate is also recorded automatically in the background, and can additionally be measured on demand: tapping "Measure" on the heart rate card asks the paired device to take a single reading. Body weight is measured on the paired smart scale. All readings are provided for general wellness and fitness reference. Body Composition When you step on a compatible NOOA smart scale, the app records your weight and charts the trend over time, with weekly, monthly, 90-day and 6-month views. The scale uses bioelectrical impedance to produce estimates of body composition, which NOOA displays alongside your weight: BMI Body fat percentage Muscle mass Body water percentage Metabolic rate Segmental readings for arms, trunk and legs These figures are estimates produced by a consumer-grade scale rather than clinical measurements. Readings from bioelectrical impedance are affected by hydration, recent meals and exercise, so they are most useful for following your own trend over time rather than as absolute values.
