Amazfit Helio Strap Smart Band Fitness Tracker

The Amazfit Helio Strap Smart Band Fitness Tracker is designed to support serious athletes, everyday fitness enthusiasts, and recovery-focused users through accurate monitoring and seamless integration with the Amazfit ecosystem. This smart band is engineered to deliver high-precision heart rate tracking, long-lasting battery performance, and lightweight comfort. Since it is worn day and night, continuous health metrics are captured each second to offer deep physiological insights without requiring any subscription fees.

With its integration across Amazfit smartwatches, the Helio Ring, and the Zepp App, a unified and uninterrupted data experience is created. Training sessions, rest periods, and daily movement are tracked consistently to support smarter workouts and better recovery. AI-powered assessments are provided to ensure that fatigue, training intensity, and recovery status are monitored with accuracy. Even when the smartwatch is removed, the Helio Strap continues operating to eliminate data gaps and keep performance records complete.

Key Features

BioCharge™ Energy Monitoring
BioCharge™ is used to interpret energy levels throughout the day. After sleep and throughout training, daily stress, and rest periods, the score is adjusted to reflect overall readiness and recovery needs.

Superior Accuracy with Upper-Arm Wear
The Helio Strap may be worn on the upper arm using the extension band to produce stability during movement. Measurement interference is reduced, and the BioTracker™ sensor is placed closer to the heart for more reliable and consistent data.

Connected Heart Rate Functionality
Real-time heart rate is transmitted to Amazfit smartwatches, compatible cycling computers, and third-party fitness equipment. Activities that do not allow wearing a watch are supported through onboard storage, which syncs directly to the Zepp App afterward.

24/7 Health Monitoring
Continuous tracking is enabled for heart rate, blood oxygen, sleep, stress levels, exertion, and overall fitness indicators. Advanced BioTracker™ technology ensures accurate biometric analysis throughout the day.

Strength Training & HYROX Modes
Repetition counts, sets, and rest periods are monitored automatically. HYROX Race Mode provides athletes with specific tools designed to support benchmark sessions and race preparation.

Zepp App Integration
All training, sleep, stress, and nutritional metrics are consolidated in the Zepp App, which serves as a free and comprehensive health dashboard. Third-party syncing supports platforms such as Strava, TrainingPeaks, adidas Running, komoot, and more.

10-Day Battery Life
A single charge supports up to 10 days of typical use, allowing continuous health insights with minimal interruption.
