As a new feature, you can now track your heart rate 24/7 directly in the app via third-party heart rate devices such as Garmin, Apple Watch, and Android devices. This means you no longer need to start and stop an activity on your smartwatch—simply enable all-day tracking, and your hearts will be calculated automatically based on continuous updates from your smartwatch, as long as it’s synchronized with the Tæl Hjerter app.
