Will the heart rate monitor monitor heart rate continuously?

The Ticwatch 2 is designed not to monitor your heart rate continuously except for in fitness mode due to power saving consideration. You can turn it on in our “Health” app when you want to check your heart rate in real time. However, when you are using our fitness app and turn to the outdoors running mode, the watch does monitor your heart rate continuously, to help you understand your heart rate conditions during your sports session.
