Best Fitness Trackers with Heart Rate Monitor: Features and Benefits
January 17, 2026
The wearable electronics market has long passed the "just a pedometer" stage. Today a wristband is more like a portable laboratory. The main focus has shifted from simple heart rate counting to complex analytics: how well the body copes with stress, whether it manages to recover overnight, and whether it's time to take a break from training.
Modern optical sensors have approached the accuracy of medical devices, although they still retain specific nuances (for example, a slight delay during sharp acceleration while running). Nevertheless, for the overall picture of health status these data are more than sufficient.

1. WHOOP MG Life Obsidian/Titanium
WHOOP MG Life Obsidian/Titanium is a specialized tool for those who prioritize analytics over visual effects. The device has no display at all, which frees the user from intrusive notifications and the constant need to check the time. The entire body is a compact sensor hidden under a SuperKnit nylon strap.
The main work happens "under the hood": the sensor scans heart rate variability (HRV), respiratory rate and skin temperature around the clock. Instead of dry heart rate numbers, the app provides a comprehensive assessment of the body's readiness for load. This allows you to accurately determine when an athlete should push harder and when the body is on the verge of overtraining and needs rest.
Features:
Heart rate monitor with heart rate variability (HRV) measurement
Pulse oximeter (SpO2)
Sleep tracking
ECG and heart screening
Stress and skin temperature monitoring
Support for yoga, cycling, running, swimming, strength training
IP68 protection (up to 10 meters)
Advantages:
Continuous 24/7 data collection without screen distraction
Calculation of recovery and strain indicators based on real physiological metrics
Ability to perform ECG directly from the wrist with the appropriate strap
Comfortable nylon strap for long wear during workouts or sleep
Deep health analytics through the app
Who it's for:
Those who train seriously and want to understand their recovery level
People monitoring stress and sleep quality in everyday life
Those who prefer a screenless device to minimize distractions

2. WHOOP 5.0 Peak Obsidian SuperKnit
The WHOOP 5.0 Peak Obsidian SuperKnit has no screen at all, and this is a deliberate choice by the brand. The device is created for those who are annoyed by endless notifications and screen glow at night. All focus here is shifted to sensors that scan heart rate variability (HRV), skin temperature and respiratory rate 24/7.
The main value of WHOOP lies not in the hardware itself, but in the app's algorithms. The system calculates the "Strain" (load) and "Recovery" (recovery) indices, literally telling the user whether to go training today or better stay in bed. The SuperKnit nylon strap allows the sensor to be worn almost unnoticed, which is critically important for obtaining accurate data during sleep.
Features:
Heart rate monitor with HRV
Pulse oximeter (SpO2)
Sleep tracking
Stress monitoring
Support for running, cycling, yoga, swimming, strength training
IP68 protection
Advantages:
Round-the-clock monitoring without the need to look at the screen
Biological age assessment and health trend tracking
Breathable strap for comfort throughout the day
Automatic calculation of recovery and load
Who it's for:
Athletes for whom detailed training analytics are important
Those who want to track the impact of stress on the body
People looking for a device for constant wear without extra notifications
Those who value in-depth recovery recommendations

3. Xiaomi Smart Band 9 Pro
Xiaomi Smart Band 9 Pro is a serious claim to leadership among affordable trackers with a large screen. The aluminum body and bright 1.74-inch AMOLED display make it look like premium smartwatches.

4. Xiaomi Smart Band 10
Xiaomi Smart Band 10 represents the evolution of the classic format. The screen has become even brighter and more responsive, while the bezels are practically invisible. The main update concerns the "internals": the updated sensor block now more accurately tracks indicators during complex types of activity such as swimming or high-intensity interval training.
The device has retained its lightness, so it is practically not felt on the wrist. Automatic activity recognition works correctly: the band itself understands when the user has switched from a walking step to running and offers to start recording the workout.

Conclusion
A modern fitness tracker has ceased to be just a toy. It is a tool of awareness. One glance at the statistics helps decide: go all out in the gym today or give the body a pause.
The choice of a specific model depends on priorities. If deep sports analytics without distractions is needed — WHOOP leads. If data visualization and versatility are important — it's worth looking at the Xiaomi or Samsung lines. In any case, incorporating such a gadget into daily routine helps manage your condition not by intuition, but based on real numbers.
