FAQs

Can fitness trackers accurately detect heart problems?

Many premium fitness trackers can detect irregular heart rhythms and record ECG readings. However, they are screening tools and should not replace professional medical evaluation.

Will fitness trackers eventually measure blood glucose without needles?

Researchers are developing non-invasive glucose monitoring technologies, but no consumer smartwatch or fitness tracker has regulatory approval for standalone blood glucose measurement at this time.

Are smart rings as accurate as smartwatches?

For metrics such as sleep, resting heart rate, and recovery, high-quality smart rings can provide comparable accuracy. Smartwatches typically offer additional features like GPS, larger displays, and workout tracking.
