To measure your heart rate, make sure your device is comfortably fitted against your wrist and not loose. The heart rate sensor on the underside of the Apex HR needs to be in direct contact with your skin. To view heart rate on your device, swipe up on the screen from the time/date screen until you see the heart icon.


In addition, your device is regularly measuring and capturing your heart rate. Your heart rate information can be viewed in the Striiv app by selecting the heart rate tile on the app home screen.


If you wish, continuous heart rate tracking can be toggled off to save battery:

With continuous heart rate turned off, heart rate readings can be triggered manually.When taking a manual heart rate reading, make sure you are sitting or standing as still as possible while the device is measuring. The less you move, the more accurate and speedy the heart rate measurement will be.
