About This Device

The Amazfit Helio Strap is a chest-worn heart rate monitor that provides accurate fitness and recovery tracking at a fraction of the cost of competitors like WHOOP. It uses optical sensors to continuously monitor heart rate, HRV, and sleep. A key advantage for Apple Health users is that HRV now syncs to Apple Health as of firmware version 3.3.10.1, making it one of the more affordable options for HRV tracking that integrates with Apple's ecosystem. The Helio Strap integrates with the broader Amazfit ecosystem including Amazfit smartwatches and the Helio Ring, and syncs with popular platforms like Strava, TrainingPeaks, and Apple Health. For caregivers on a budget, the Helio Strap offers solid health monitoring without ongoing subscription fees.

Pros

  • No subscription required - one-time purchase
  • HRV syncs to Apple Health
  • Accurate chest-worn heart rate sensor

  • Works with Amazfit ecosystem

Cons

  • Only average HRV imported (not detailed overnight)
  • Less polished app experience
  • Chest strap may be less comfortable for 24/7 wear
  • Recovery score may not appear reliably
