For
an accurate heart rate reading make sure the sensors are touching your skin.

The idea is pretty good: they sit snugly in your ear canals and push the optical heart rate monitor against your skin to give one of the more

The Apple Watch has a heart rate monitor that uses a technology called photoplethysmography to obtain

This device is meant to give a more

It does have optical heart rate sensors, and Fitbit says the watch will take a heart rate reading every five seconds during the day and every second during workout sessions, which in theory should give wearers more
accurate heart rate readings.
