In a world dominated by smartwatches and fitness bands with vibrant displays and endless notifications, the Amazfit Helio Strap takes a radically different approach. It’s a screen-free wearable designed for athletes and performance-focused users who want uninterrupted, high-fidelity tracking without the distractions of a digital interface. This isn’t just minimalism for aesthetic’s sake—it’s a deliberate design philosophy that puts physiological data and recovery insights front and center.
Design That Disappears Into Your Routine
The Helio Strap is featherlight at just 20 grams, making it one of the most comfortable wearables for all-day and all-night use. Its fiber-reinforced polymer body is paired with a 22mm nylon strap that’s breathable, secure, and built to withstand intense workouts. The absence of a screen means there’s no need to worry about scratches, glare, or battery drain from display usage. Instead, the strap becomes a passive yet powerful companion that quietly collects data while you focus on your training.
For users who want even more accurate readings—especially during high-intensity or grip-heavy workouts—Amazfit offers an optional armband extension. This allows the strap to be worn closer to the heart, minimizing interference from muscle contractions and wrist movement. It’s a thoughtful detail that reflects the brand’s commitment to precision.
BioTracker™ 6.0: The Heart of the Strap
The Helio Strap is powered by Amazfit’s BioTracker™ 6.0 PPG sensor, which delivers per-second heart rate tracking with remarkable accuracy. This high-frequency data capture is ideal for athletes who rely on heart rate zones for training, recovery, and performance optimization. Beyond heart rate, the sensor also tracks blood oxygen saturation (SpO₂), stress levels, and sleep stages—including REM, deep, and light sleep.
This comprehensive health monitoring makes the Helio Strap a valuable tool not just for workouts, but for understanding how your body recovers and adapts over time. Whether you’re training for a race or managing fatigue, the strap offers insights that go far beyond step counts and calorie estimates.
BioCharge™: Your Real-Time Energy Score
One of the standout features of the Helio Strap is BioCharge™, Amazfit’s proprietary energy monitoring system. This algorithm synthesizes data from sleep quality, exertion levels, and stress to generate a dynamic energy score throughout the day. It’s a simple yet powerful metric that helps users decide when to push harder and when to prioritize rest.
Unlike static recovery scores found in other wearables, BioCharge™ evolves in real time, adapting to your activities and physiological state. It’s especially useful for athletes who train multiple times a day or follow periodized training plans, offering a clear snapshot of readiness and recovery.
Workout Modes and Strength Training Intelligence
Despite its minimalist design, the Helio Strap supports 27 workout modes, including running, cycling, yoga, HIIT, and strength training. It’s particularly optimized for HYROX athletes, with a dedicated HYROX Race Mode that tracks performance across race segments and training modules.
Smart strength training features automatically detect reps, sets, and rest periods, feeding into the Zepp App for post-workout analysis. Users can review metrics like VO₂ max, training load, recovery time, and workout effect—data typically reserved for high-end smartwatches.
Seamless Integration with the Zepp Ecosystem
The Helio Strap syncs effortlessly with the Zepp App, which acts as the central hub for all health and fitness data. The app is free to use and compatible with Android 7.0 and iOS 15 or later. It offers AI-driven insights across fitness, sleep, stress, and nutrition, helping users make informed decisions about their training and recovery.
The strap also integrates with third-party platforms like Strava, Google Fit, Apple Health, TrainingPeaks, adidas Running, and komoot. This makes it easy to share data across your fitness ecosystem, whether you’re tracking progress, syncing with coaches, or analyzing trends.
Battery Life That Keeps Up With You
Battery life is another area where the Helio Strap excels. With up to 10 days of usage on a single charge, it’s built for endurance. This is especially valuable for athletes who travel, train frequently, or simply prefer not to charge their devices every night. Charging is quick and easy via a magnetic base, and the strap connects via Bluetooth 5.2 for stable data transfer.
Built for Comfort, Durability, and Water Resistance
The Helio Strap is rated 5ATM water-resistant, making it suitable for swimming, showering, and exposure to sweat and rain. Its rugged build and minimalist design make it ideal for high-intensity environments, from the gym to the trail. And because it lacks a screen, there’s no risk of glare or display damage during outdoor activities.
A Companion, Not a Distraction
What sets the Helio Strap apart is its philosophy. It’s not trying to replace your smartwatch or smartphone—it’s designed to complement them. When paired with devices like the Amazfit Balance 2 or Helio Ring, it becomes part of a multi-device training system that ensures uninterrupted data collection across different contexts. For example, if you remove your smartwatch to sleep more comfortably, the Helio Strap continues tracking your heart rate and sleep stages, maintaining continuity.
This synergy is especially useful for athletes who want granular insights without compromising comfort or battery life. It’s a thoughtful approach that respects your focus and adapts to your rhythm.
Who Is It For?
The Helio Strap is ideal for athletes, fitness enthusiasts, and biohackers who value data integrity, comfort, and ecosystem integration. It’s not for casual users who want visual feedback or lifestyle features like notifications and music control. But for those who train hard, recover smart, and prefer clarity over clutter, it’s a compelling choice.
Priced at ₹8,999 in India, the Helio Strap offers premium tracking capabilities at an accessible price point. It’s available through Amazfit’s official website and select tech and sports retailers.
