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.
Heart-rate tracking is now a standard smartwatch feature, but accuracy depends on activity, watch fit and movement.
The guide compares six models: Amazfit Bip Max, Samsung Galaxy Watch 7 and 8, Garmin Instinct 2 Solar, Google Pixel Watch 4 and Apple Watch Series 11.
The Amazfit Bip Max uses a BioTracker 6.0 sensor with readings close to a chest-strap reference, plus up to 20 days of battery life.
The Garmin Instinct 2 Solar lasts up to 28 days (unlimited with solar) and has a rugged build suited to outdoor training.
The article advises treating smartwatch heart-rate readings as fitness data rather than medical measurements.
