Track heart rate with accuracy, stay protected by intelligent alerts, and train strategically with 5-color zone indicators.

Seamlessly connect three devices via 3-channel Bluetooth, and choose from 3 tailored sizes for a perfect fit.

The H613 heart rate monitor isn’t just a sensor—it’s your invisible coach and performance partner, guiding every step of your journey.

New Algorithm Upgrade, Precise Heart Rate Tracking
The H613 heart rate monitor features a new-generation, self-developed heart rate algorithm. Unlike traditional optical sensors that rely on indirect monitoring, it uses proximal ECG signal direct acquisition technology to capture heart rate fluctuations in real time. Combined with dynamic noise-reduction filtering, it suppresses interference signals even during high-intensity interval training or sweat-heavy cycling, delivering highly precise and stable heart rate tracking. Every heartbeat is measured accurately, providing reliable data for scientific training.
*This heart rate sensor is for sports use only and cannot replace medical devices.

17h Offline Storage: Unrestricted Training, No Data Loss
A built-in storage chip supports 17 hours of offline recording. During outdoor cycling, mountain hiking, or gym workouts, the sensor operates independently, with no need for a phone or connected device—continuously tracking heart rate fluctuations. After your session, connect to the OnelapFit app to automatically sync and view a complete report (including workout duration, calories burned, average/max heart rate, heart rate zone distribution, etc.). Stay focused on training while seamlessly managing your data—no device dependency required.

Versatile Sport Compatibility?Precision from Every Angle: H613 heart rate monitor is suitable for multiple sports scenarios, supporting different types of exercises including high-intensity intervals (boxing/spinning), endurance training (cycling/hiking), static control (yoga/Pilates), and strength training ect.

Smart Heart Rate Alert, A Safety Boundary for Every Breakthrough
Heart rate alerts help create a protective boundary for safer training. 
The H613 heart rate monitor is equipped with a heart rate warning function that supports customizable safe heart rate thresholds. When the heart rate reaches the preset value during exercise, the sensor triggers a synchronous buzzer alert, sounding a timely "fatigue alarm" to avoid cardiopulmonary overload risks. Like an "invisible coach," H613 heart rate monitor uses data to build the line of defense for sports safety.
*Heart rate warning values are set in the OnelapFit APP.

Connect Three Devices, Share Data Seamlessly
The H613 heart rate monitor supports ANT+ and Bluetooth standard protocols, enabling simultaneous data recording by ANT+ devices and apps with stable transmission.
The Bluetooth channel supports up to 3 devices connected simultaneously, eliminating the need for manual device switching or data import. Free form the hassle of data fragmentation of multiple devices. For example, H613 heart rate monitor can connect to a sports app, smartwatch, and treadmill simultaneously to share heart rate data during gym workouts.

Anti-bacterial, Anti-odor & Anti-slip: Move Freely, Sweat Fearlessly 
The H613 heart rate monitor adopts antibacterial and deodorizing technology, effectively inhibiting microorganisms to maintain long-lasting freshness. The chest strap is embedded with non-slip silicone that reduce displacement during both high-intensity workouts and long-term wear, minimizing the risk of abrasions caused by over - tightening. Moreover, a stable wear also ensures more accurate data monitoring.  
Deodorizing Performance 
Eliminates 93.7% of ammonia, 89.4% of acetic acid, 95.2% of isovaleric acid, and 99.3% of 2-nonenal. 
*Tested according to ISO-17299.
Bacterial Inhibition Rate 
Inhibits 94.35% of Candida albicans, 99.13% of Escherichia coli, 99.55% of Staphylococcus aureus. 
*Tested according to ISO-20743. 

Crafted Design for Comfort and Durability
The ergonomic curved profile sets a new benchmark for sports monitoring. With a slim 10.8mm to 8mm tapered design, it fits closely against the chest for stable, accurate tracking. Whether you’re running, cycling, or lifting, it moves with you to ensure friction-free performance.
The sealed battery compartment is rated IPX7 waterproof, tough enough to withstand rain or heavy sweat. At just 12.4g, its ultra-light build offers a barely-there feel for unrestricted motion. Built with advanced materials, it resists scratches and wear, so you can focus fully on your training.
