The Full Picture
Worn on the bicep, the Helio Strap reads heart rate more accurately than any wrist device — valuable for intervals and sleep. The BioCharge score condenses recovery into one number, and with no subscription it costs $99 once. If you already wear a watch for the time, this is the tracker to pair with it.
