Price: Waitlist for late 2022

Description:

Your ring measures heart rate, heart rate variability, sleep, respiration, temperature, blood oxygen, steps and calories. It can tell you why you slept the way you did, and that your resting heart rate’s higher after a few glasses of wine. It will let you know if your body temperature goes up (so find your partner if you’re trying to conceive!).

It can show the doctor that your symptoms aren’t in your head—because you’ve got proof in your phone. Your wearable can even show you how your heart health improves with increased exercise over time.
