The Google Pixel Watch 3 impressed me with how accurately it tracks heart rate, and I was eager to see if the newest model would hold up. After reviewing the Pixel Watch 4, I can confirm it’s easily one of the most precise wrist-based monitors I’ve tested. It consistently delivers readings that match my dedicated chest straps, which are considered the gold standard for heart rate tracking. That level of accuracy makes the Pixel Watch 4 one of the most reliable heart rate monitors I’ve worn in any form. Plus, the device is backed by Fitbit’s robust health platform and Google’s improved algorithms, for a well-rounded, reliable experience.
While reviewing the new model, I tested the accuracy throughout a range of activities, including running, cycling, rowing, strength sessions, and daily wear. No matter the context, the heart rate data remained impressively stable and precise. Even during workouts with lots of movement or wrist flexion, where most wearables struggle, the watch matched trusted monitors and offered a much comfortable fit than a chest strap.
Google’s latest smartwatch holds up even against dedicated chest straps.
Beyond accuracy, Fitbit’s built-in platform also adds meaningful value, from real-time heart rate zones during workouts to post-exercise metrics like Cardio Load and Readiness. The watch also auto-detects many common workouts, offers ECG support, and accurately tracks additional metrics like sleep and stress. Add in improved battery life and a powerful Wear OS experience, and the Pixel Watch 4 easily earns its place on my wrist.

Polar H10: The best heart rate monitoring chest strap
Simple setup • Flexible compatibility • Accurate heart rate tracking
MSRP: $89.99
The Polar H10 is a chest strap you can set and forget, as long as you get the fit right
Polar’s H10 is a tried and true chest strap that’s outlived some of its launch features. It’s our team’s go-to heart rate monitor when testing other wearables thanks to the simple setup, long-lasting battery life, and flexible compatibility with watches from Coros, Suunto, and more.
Positives
- Multiple simultaneous Bluetooth connections
- ANT+ running dynamics
Cons
- Some features need pairing with a GPS fitness watch.
The Polar H10 isn’t the most convenient option, but when it comes to heart rate accuracy, it’s still the device I trust most. I’ve used the H10 as my control for years while testing countless fitness trackers, and it continues to outperform nearly every wearable on the market. It’s the gold standard for a reason, delivering consistent, precise readings no matter the activity. If you can get on board with strapping a band around your torso, this is my favorite pick.
I’ve worn the H10 during long runs, HIIT workouts, cycling sessions, and strength training, and it never falters. Because it sits close to the heart and uses electrical heart rate monitoring, it avoids many of the issues that plague wrist-based monitors, especially during workouts with tons of arm movement or grip-intensive exercises. Think weight lifting or even rowing. If heart rate accuracy is your top priority, and especially if you’re data mining or targeting specific zones, the Polar H10 is still the most trustworthy tool you can use.
Because it sits close to the heart, the Polar H10 delivers where wrist-based wearables might falter.
I don’t personally love the feeling of a chest strap, but as straps go, the Polar H10 is comfortable enough for extended wear, and Polar’s mobile app offers basic insights for standalone use. But where the H10 really shines is in pairing with third-party fitness platforms, GPS watches, and apps like Strava. It supports both Bluetooth and ANT+, so it plays well with just about any device.

Wahoo Trakr Heart Rate: The best rechargeable heart rate monitoring chest strap
Reliable, accurate heart rate recording • Built-in rechargeable battery • ANT+ and multi-Bluetooth connectivity
MSRP: $89.99
A reliable HR monitor.
The Wahoo Track Heart Rate is a comfortable, reliable, and versatile heart rate chest strap.
Positives
- Reliable, accurate heart rate recording
- Built-in rechargeable battery
- ANT+ and multi-Bluetooth connectivity
Cons
- No onboard storage
- Proprietary charger
- Only available in one color
The Wahoo Trackr Heart Rate Monitor is another standout chest strap that combines exceptional accuracy with the convenience of a rechargeable battery, a feature that sets it apart from many traditional chest straps. The rechargeable design makes it a hassle-free choice for anyone after precision as much as long-term convenience. Throughout my testing, it consistently delivered heart rate data that matched other trusted devices and offered reliable connectivity with no dropouts.
Greatly improving on past models, Wahoo’s Trackr maintains a stable connection throughout every session, making it a much more dependable option than others I’ve tested from the company. I wore it for everything from running and cycling to strength and HIIT workouts, and was pleasantly surprised by the perfect data it recorded. Meanwhile, the soft, adjustable strap fits comfortably and securely, though wetting the sensors before use remains a necessary nuisance.
The Trackr delivers top-tier precision but with a convenient, rechargeable battery.
With up to 100 hours of battery life and a simple magnetic charging cable, the rechargeable lithium-ion battery eliminates the hassle of coin-cell replacements, a convenience I really appreciate. It also means less e-waste, and I truly never know how to safely dispose of batteries. It supports both ANT+ and Bluetooth, allowing easy pairing with a wide range of devices and apps. However, it’s not a good choice for swimmers as it doesn’t support any onboard data storage, and broadcasting isn’t reliable through the water.

Polar Verity Sense: The best heart rate monitoring armband
Very comfortable • Accurate HR tracking • Good battery life
MSRP: $99.95
Comfy HR tracker for your arm.
The Polar Verity Sense is a reliable, comfortable heart rate tracker that slips onto your arm.

Cons
- Strange cradle charger
- Can’t be worn with all clothes
For heart rate accuracy without the tight squeeze of a chest strap, the Polar Verity Sense is the best armband-style heart rate monitor I’ve tested. Worn around the bicep or forearm, it offers a strong balance of comfort, accuracy, and convenience, making it a good alternative for anyone who finds chest straps restrictive or wrist sensors not quite up to snuff.
The Verity Sense uses optical heart rate tracking but consistently delivers data that rivals chest straps, especially when worn snugly. In my experience, it’s among the most accurate optical sensors available, even during high-intensity workouts and exercises with a lot of upper body movement (like when I force myself to begrudgingly do burpees). It’s a go-to for me in situations where comfort matters, like longer cardio sessions or mixed training days.
An armband rather than a chest strap, the Verity Sense strikes the perfect balance of comfort and accuracy.
The band itself is soft, adjustable, and stays firmly in place without slipping or digging in. It’s lightweight enough to forget about during a workout and secure enough to handle everything from tennis to HIIT. Like the Wahoo Trackr, it features a rechargeable battery (but with only up to 20 hours of runtime) and also supports both Bluetooth and ANT+. And while aesthetics rarely matter in heart rate tracking, the Verity Sense does come in a few color options—an appreciated bonus if you care what your gear looks like in the gym.

The insights and guidance also improve the longer you wear the device.
The Oura Ring 4 delivers accuracy in a sleek, comfortable design that’s easy to wear 24/7.
Meanwhile, its slim, comfortable design makes it easy to wear 24/7, and it blends effortlessly with my everyday jewelry. The battery also lasts me about four full days, so I don’t have to obsess over a charging schedule, which is a huge plus for something you’re supposed to wear continuously. Plus, the ring’s water resistance means I can keep it on through showers and sweaty workouts, though I usually remove it when swimming out of fear of losing it.

What to look for in a good heart rate monitor
Kaitlyn Cimino / Android Authority
Whether you want to track your resting heart rate, monitor your sleep, or gather the most precise data during workouts, there are plenty of reasons to invest in a heart rate monitor. But not all sensors are created equal, and in my experience, form factor isn’t the only consideration. If accuracy is your top priority, chest strap monitors remain the benchmark. These devices offer superior precision, particularly during high-intensity workouts, and are capable of detecting subtle fluctuations that wrist-based wearables may miss.
On the other hand, wrist-worn trackers and fitness smartwatches provide a broader range of features and are more convenient for all-day wear. Many models still deliver reliable data, and they bundle heart rate tracking with tools like sleep insights, activity tracking, notifications, and much more.
Here are the key factors to consider when shopping for a heart rate monitor:
- Accuracy: Precise heart rate data matters, especially during workouts, so look for devices known for dependable tracking. Chest straps tend to outperform wrist-based wearables, but some modern smartwatches are very capable.
- Sensor type: Wrist-based monitors typically use optical sensors, while chest straps use ECG technology for more reliable readings.
- Form factor: Beyond heart rate tracking, many devices offer sleep monitoring, stress tracking, heart rate variability, and VO₂ max estimates. Do you want a well-rounded smartwatch or a straightforward chest strap?
- Comfort and fit: The device needs to be comfortable enough to wear consistently. Chest straps should stay secure without pinching, and wrist devices should fit snugly without trapping sweat.
- App support: A strong companion app makes a big difference. Look for clear data visualization, long-term tracking, and easy syncing with the services you use, such as Strava.
- Connectivity: Some devices offer Bluetooth, others ANT+, and a few support both. If you want to pair with gym equipment, watches, or bike computers, check compatibility first.
- Water resistance: If you plan to swim or sweat heavily, make sure your monitor is rated for water resistance. 5 ATM or IP68 is a good starting point.
- Battery life: Some chest straps last for months on a single coin-cell battery, while most fitness trackers and smartwatches will need recharging every few days. Consider what level of convenience works best for you.
