Six Smartwatches Worth Watching for Heart-Rate Tracking Accuracy

Smartwatches are like little computers you wear on your wrist.

Many of them can check how fast your heart is beating.

This is called heart-rate tracking, and it is now very common on smartwatches.

It helps people see how hard their body is working during exercise and through the day.

The article looked at six smartwatches, including the Amazfit Bip Max, Samsung Galaxy Watch, Garmin Instinct 2 Solar, Google Pixel Watch and Apple Watch.

Some are made mostly for fitness and last a very long time on one charge.

Others have many extra features but need to be charged more often.

The watches use lights and sensors on the back to measure your pulse.

The article says these readings are good for fitness, but they are not the same as a doctor's medical check.
