Your health, in harmony ASUS VivoWatch SP is an intelligent wearable health tracker that offers 24/7 health and fitness monitoring and insights to help you maintain a healthy lifestyle and achieve fitness goals. Together with the ASUS HealthConnect app, you can track blood pressure, heart rate, exercise, sleep and a variety of other health categories in an intuitive and easy way. Exclusive ASUS HealthAI technology then provides personalized health-management tips based on health measurements, manual recording and personal habits. Stylish and durable, with up to 14-day battery life and a swim-proof design, VivoWatch SP is designed to be a 24/7 health companion that goes anywhere. It accepts standard watch bands and features a variety of changeable faces, giving you a powerful health companion that reflects your individual style. Exercise heart rate and pulse transit time (PTT) VivoWatch SP features a pair of electricalgraphy (ECG) and photoplethysmography (PPG) sensors, enabling it to calculate pulse transit time (PTT) as well as measure heart rate, sleep and activity and stress levels throughout the day, giving you a variety of insights for better health management. Body Harmony Index With its ECG sensor, VivoWatch SP measures your body's sympathetic and parasympathetic response and calculates a Vitality Index and Relax Index in just one minute. The Vitality Index is a score of your resiliency to stress, while the Relax Index is a score of your current relaxation or stress level. The two scores are then used to calculate a Body Harmony Index that gives you an easy to understand view of your body's overall stress response. Automatic health measurements You can set VivoWatch SP to perform automatic pulse transit time (PTT) measurements at regular intervals and receive notifications of the results, giving you an easy and convenient way to stay informed about your health. Smart health-management tools Medication tracking and reminders Enter your medicine schedule in the ASUS HealthConnect app, and VivoWatch SP will remind you when it’s time to take each medication, helping you to keep a regular schedule and never miss a dose. Health data and personalized analysis sharing Share selected health data with your family, doctor or anyone you choose, securely and easily. This long-term information may offer additional insights over individual blood-pressure measurements done at a clinic. Cloud data storage Back up your health data to the cloud and easily download it to any of your mobile devices. Google Fit and Apple Health support Better flexibility for health data management Personalized sleep-quality analysis VivoWatch SP tracks your sleep duration and quality, giving you insights to help you get your best night’s sleep. By tracking your heart rate in the background, VivoWatch SP can determine when you are winding down and begin automatically tracking your sleep. It also uses your pulse oxygen and heart rate measurements to determine how deep and restful your sleep is. Movement throughout the night is another indicator of sleep quality, so VivoWatch SP tracks your motion and records how many times you turn from side to side each night. The sleep information VivoWatch SP tracks syncs automatically to the ASUS HealthConnect app, where you can review your daily sleep summary and see weekly statistics.
