Amazfit Helio Strap review

The Helio Strap is the cheapest screenless option on this list, and it leans toward training more than daily step counting. Amazfit says it tracks heart rate every second and can be worn on the upper arm, closer to the heart, to reduce movement interference when the wrist is flexing or gripping during lifts and hybrid workouts. It can broadcast live heart rate to compatible smartwatches, cycling computers, treadmills and apps, and it stores up to 21 days of heart rate offline, which helps for team sports where you leave the phone in a bag. Recovery tracking covers sleep, HRV, blood oxygen and stress, and the Zepp App adds VO2 max, training load, training effect and recovery time across 50+ sports modes. Amazfit rates the battery at up to 10 days and the water resistance at 5 ATM, with no required subscription. If your main goal is a daily step count on the wrist, the Inspire 3 is a better fit for less.
