Easy & Intuitive Heart Rate Monitoring
Steel HR offers automatic heart rate tracking throughout the day and night to help you monitor health and optimize performance. Explore daily heart rate variance and heart rate during sleep, and view your heart rate in real time during workouts. After each session, assess your overall performance with a personalized in-app report.
Automatic Activity & Sleep Tracking
With automatic recognition of steps, run, swim, distance and calories burned, a quick glance at the watch's activity dial lets you know how active your day has been. At night, the watch tracks sleep, so you can wake up each morning to a comprehensive report of sleep cycles, duration, wake-ups, and heart rate.
Personalized Smartphone Notifications
Steel HR provides enhanced connectivity with text, call and calendar alerts, as well as a silent vibrating alarm to help you get going in the morning, or off to your next meeting on time.
Style Built to Last
Steel HR takes style seriously. With a stainless steel case, chrome hands, and soft silicon wristband, this watch fits all aspects of your life, from your gym session to a night out. Simply press the watch button to scroll through your data — date, heart rate, steps, distance, calories burned, and alarm time, on the watch's digital display.
Long-Lasting & Water-Resistant
With up to 25 days of battery on a single charge, Steel HR has the longest battery life of any heart rate tracker on the market. The watch also offers an additional 20 days of activity tracking in power reserve mode, and is fully rechargeable in just 2 hours. And because Steel HR is water-resistant up to 50 meters, you never have to worry about taking it off.
A Coach You Can Trust
Steel HR automatically syncs with your smartphone, so you can view all activity, sleep, and heart rate data instantly in the Health Mate app. Health Mate acts as your coach to help you set goals, stay motivated with insights and advice, and connect with over 100 health and fitness partner apps.
