Zonas: Heart Rate Zone Tracker

Zonas puts your heart rate zone where you can actually see it: on your Lock Screen, in Dynamic Island, and floating over any app with Picture-in-Picture. Start a workout, put your phone away, and keep your effort visible while you change music, follow a workout video, check a message, or use another app. PICTURE-IN-PICTURE HEART RATE A floating heart rate zone overlay stays on top of other apps, so you do not need to keep Zonas open during training. LOCK SCREEN & DYNAMIC ISLAND Your heart rate and zone update live through Live Activities. On iPhone models with Dynamic Island, your current zone stays visible while you use your phone. REAL-TIME HEART RATE ZONES Zonas calculates five training zones automatically using the Karvonen formula when resting heart rate is available, or percent of max heart rate when it is not. You can also set custom zone boundaries. BLUETOOTH & APPLE WATCH Use a standard Bluetooth heart rate monitor such as Polar, Garmin, Wahoo, Coospo, and other chest straps or arm bands. You can also start workouts from the Apple Watch companion app and mirror heart rate to iPhone. WEEKLY CARDIO GOALS Track weekly cardio minutes using WHO guidance: 150-300 minutes of moderate activity, or equivalent vigorous activity. Zonas converts vigorous minutes to moderate-equivalent minutes automatically. DOZENS OF WORKOUT TYPES Running, cycling, swimming, HIIT, rowing, yoga, strength training, hiking, martial arts, and more. PRIVACY FIRST No account. No cloud. No tracking.
