The app “HRT - Heart Rate Training” helps you keep the right pace while training and competing. The app tells you what your current heart rate is using audio. You select how often you want to be alerted and you select whether you want the information in bpm (beats per minute) or % of your maximum heart rate. To use the app you need a bluetooth smart heart rate device, for example Wahoo Blue HR or Polar H7. Many watches can also broadcast heart rate to your phone. Check in the user manual whether your can. The app also features a Fartlek training program. This is a fun way of doing intervals. You will find many articles describing how to do heart rate training on the internet, by searching for ”Heart Rate Training” for example. The main idea is that you get different results depending on what heart rate you have compared to your maximum heart rate. When competing, staying in an elevated heart rate zone too long can decrease your performance. One of the advantages with the HRT app is that you can select how often you want to be alerted and be able to adapt your performance immediately. The app is easy to use and is as suitable for professional athletes as for amateurs. The app also features a customizable heart rate recovery mechanism. Measure how fast your heart rate drops after training. It is normally considered to be a sign of improving physical condition if your heart rate drops faster. The app is free. If you use it more than 10 times, a dialog box will be displayed giving you the option to support the development of the app. You can continue to use the app for free by dismissing the dialog box. After an hour you will also hear a short audio message asking you to buy the app such that my wife can buy herself new shoes. This message will then be announced gradually more often, finally every 10 minutes.

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.
