Amazfit HELIOSTRAPBK Helio Strap Fitness Tracker - Black

The Helio Strap is built for those who train hard and recover smarter. Designed for precision, endurance, and everyday versatility, it delivers industry leading accuracy, extended battery life, and a lightweight, comfortable fit that moves with you. Worn all day, it provides continuous heart rate monitoring and deep health insights without the hassle of subscriptions.
More than just a fitness tracker, the Helio Strap is a vital part of the Amazfit ecosystem. Seamlessly integrating with Amazfit smartwatches, the Helio Ring, and the Zepp App, it powers a complete training system designed to help you train with purpose, recover effectively, and repeat with confidence. The Helio Strap features a water-resistance grade of 5 ATM, meaning it can withstand pressure equivalent to 50 meters of static water depth for up to 10 minutes. Recovery Redesigned
Unlike competitors that rely on a single device, the Amazfit Ecosystem offers a fully integrated training system that seamlessly connects your smartwatch, like the Balance 2, with the Helio Strap and other devices through the Zepp App. This ensures uninterrupted data collection whether you're training, sleeping, or resting - even when your watch is off.
By eliminating data gaps and extending battery life, the system delivers accurate heart rate monitoring, fatigue assessment, and recovery analysis. With real-time insights and AI-powered recommendations, it empowers you to train smarter, recover better, and repeat every day. BioCharge Energy Monitoring
