Show HN: Heart Rate Zones Plus – The first iOS app...
Not sure if it is mentioned in the app description, but how is heart rate calculated? Using the Apple Watch?

It uses Apple HealthKit, so anything that writes heart rate data to Apple Health. In most cases this will be Apple Watch, but other devices with heart rate sensors should work too.
