Heart Rate Monitor: HR Zones

See your heart rate zones live, in big numbers you can read from across the room. Heart Rate Monitor connects to your Bluetooth chest strap, armband or watch and shows which zone you're in, second by second, for running, cycling, treadmill, spinning, rowing or any cardio and HIIT workout. WORKS WITH YOUR SENSOR Any heart rate sensor using the standard Bluetooth heart rate profile works, with no extra app or account. For example the Polar H10, H9, OH1 and Verity Sense, the Garmin HRM-Pro and HRM-Dual, the Wahoo TICKR, and watches that broadcast heart rate, like Garmin Forerunner, Venu and fēnix or COROS watches. The app tells you which sensor is the one you're wearing, shows its battery, and connects to your last one by itself. LIVE HEART RATE ZONES • Your heart rate in the color of its zone, from Zone 1 to Zone 5 • A zone bar that zooms on your current zone, so you see where you are within it • Live chart of the last minutes, with every zone in view or zoomed on your effort • Time in each zone, average and max heart rate, and calories as you go • Beat-to-beat HRV (RMSSD) from chest straps that send it • Zones from your max heart rate, or from your heart rate reserve (Karvonen) with your resting heart rate • Don't know your max heart rate? Estimate it from your age AFTER YOUR WORKOUT • Heart rate recovery: how far your heart rate drops in the minute after you stop • Workout chart you can pinch to zoom, down to every second • Intervals found for you: each effort's peak, low, time up and time down • Highlights and records: your longest workout, your hardest effort, your longest stretch in one zone • Every workout saved by month, with a title and notes • Share a workout as an image with your zones, chart and stats PRIVATE BY DESIGN Your heart rate, workouts and profile stay on your phone. No account, no sign-up, nothing stored on a server. Bluetooth is only used to connect your sensor; the app never uses your location. Built for zone 2 training, threshold intervals and easy recovery days, for anyone who trains with a heart rate strap and wants to see their zones clearly. The app is free with ads.
