There are dozens of accessories designed for the Apple Watch, but none of them has passed the U.S. Department of Health and Human Services.
Finally, the company AliveCor managed to present a bracelet that did not leave the Ministry representatives indifferent.
The KardiaBand is a special strap for the Apple Watch.
All you need to do to get heart rate information is put your finger on the special area on the bracelet. The KardiaBand will show you all the heart rate information in real time.
AliveCor has priced its development at a hefty $199, but to date it is the only accessory of its kind. For the KardiaBand you have to buy a subscription for $99 per year. Without it, it won't work. The accessory is already available on Amazon.
