The Best Heart Rate Monitors to Check Your Cardiac Health

Tech-news buying guides, exercise, Shopping, Sports, workout August 25, 2025

FAQS

We tested and recommend all of the heart rate monitors below, which do a pretty impeccable job. But what do all these terms mean?

Heart rate zones: If someone tells you they’ve been doing 80/20 training, they’ve been doing heart rate zone-based workouts. Heart rate zones are an easy way to break down your range of effort during exercise. Zones go from 1 to 5, with 5 indicating working at 90 to 100 percent of your maximum heart rate. Zone 2 represents training at 60 to 70 percent of maximum heart rate and represents light training. 80/20 training is intended to build endurance and means that 80 percent of your runs should be in Zone 2. If your heart rate monitor doesn’t tell you your zone, you can calculate it using Polar’s simple tool.

Maximum heart rate: Some monitors can inform you of your maximum heart rate, which is the number of beats your heart can reach during exercise. This is useful for knowing when you’re training at peak intensity and can be used to create heart rate zones. Factors like your age and fitness level can influence what that maximum heart rate will be. You can generate an estimate of your maximum heart rate by simply subtracting your age from 220 and use that at a starting point.

VO₂ max: The term VO₂ max stands for maximum rate of oxygen your body can consume during exercise; the higher the better. It provides a useful indicator of your ability to sustain intense effort for long periods. Calculating this accurately is done in lab conditions, so heart rate monitors and watches often use their own algorithms to approximate that lab testing.

Heart rate variability: Heart rate variability measures the intervals between heart beats and is measured in milliseconds. High HRV readings are considered better than lower ones, because it means that the body is responding in a resilient way to stress. However, your HRV readings can differ widely from one person to another because they can be influenced by age, fitness level, or even when the measurement was taken.

Resting heart rate: This is the number of times your heart beats in one minute when at rest, which is a simple indicator of your current level of cardiovascular fitness and general well-being. Typically, your heart rate is supposed to sit anywhere from 60 to 100 bpm at rest. A low resting heart rate is associated with athletes, because the heart has been trained to be more efficient. But an uncharacteristically low or high RHR could mean that something is not quite right.

Calories burned: A heart rate monitor looks at your effort based on your heart rate and uses the company’s own algorithms to offer an indicator of how many calories you’ve burned during a workout. Heart rate is one of the strongest, if not the strongest indicators of effort, which means a heart rate monitor is one of the most accurate ways to get this information.

OPPO Find X9 Ultra Camera Details Revealed Ahead of India Launch

After a stellar Find X9 launch, the OPPO Find X9 Ultra will soon be available in India, bringing some exciting changes to the device, specifically aimed at boosting its camera performance. The firm is shifting its focus to hardware to enhance optical zoom capabilities, rather than relying too heavily on software.

The star attraction is QPPS, a new periscope architecture that enhances the feasibility of extended-range optical zoom. In most smartphones, optical zoom is achieved using a single prism that deflects the light path horizontally. Although this design boosts zoom range, it is constrained by the space available in the phone body.

What is QPPS?

The QPPS (Quintuple Prism Periscope Structure) is designed to extend zoom using a smarter internal setup. In the camera body, the light reflects five times before hitting the sensor, thereby increasing the length of the optical pathway. Furthermore, the OPPO Find X9 Ultra can increase its focal length without compromising its thinness. The phone, therefore, can achieve true 10x optical zoom, equivalent to a 230mm lens.

An additional benefit of optical zoom is its ability to maintain image quality. Since the zoom is handled by the camera hardware, there’s less need for cropping or digital enhancement. This leads to sharper and more natural images. In everyday use, it improves shots of distant subjects and creates a pleasing background blur. It also ensures that image quality doesn’t drop suddenly as you move between zoom levels.

A multi-reflection system improves zoom, but it also complicates light handling. Each reflection point can introduce distortion or scattered light, which can affect the final image. Without proper control, this could lead to reduced sharpness and contrast.

To overcome this, OPPO uses a refined optical design that keeps light under control throughout its path. By applying highly precise adjustments, the camera is less affected by light, ensuring image quality. It means that you can take better shots with high zoom levels.

Camera

The phone has a 200 MP resolution camera that delivers high-quality photos, a 3X zoom camera that is useful for shooting in low light, and an ultra-wide camera that captures a wider view.

These elements combine to form an equilibrium system applicable to various situations. In cases where one is shooting portraits, scenery, or distant objects, the camera can do all that. Moreover, it features 4K Dolby Vision video recording capabilities, hence being suitable for photography and video recording.

Software

In this camera system, software plays a supporting role. The LUMO Image Engine focuses on refining the image rather than artificially generating details. Instead of using software to create details that do not exist in the image, the technology uses high-powered hardware to generate the main image. This helps create a more realistic image with natural details. Afterward, the software is used to enhance the final image through minor adjustments to colors and brightness.

Software often plays a bigger role than the camera hardware itself. However, OPPO approaches this issue from a different angle, focusing more on hardware advancements. It results in more realistic and natural pictures. Also, there is better performance during long-range zoom operations.

Anthropic Has Added Several More Religions on Its Quest to Inject Perfect Morals into Claude
The original mysterious black box wasn’t an AI model at all, but the Kaaba, the black cube at the center of the Sacred Mosque of Mecca. Prior to Muhammad’s conquest of Mecca, the Kaaba was a sort of all-purpose repository of 360 sacred symbols from around the region. If you were, say, a busy merchant on his way to Medina, whatever the great spiritual truths of the universe may be, they were in there somewhere, so a prayer to the Kaaba had you covered in the god department and you were good to go. Anthropic seems to be doing something along these lines with Claude. Last week, representatives from Anthropic—along with OpenAI—attended an event in New York called the “Faith-AI Covenant” roundtable. The New York Board of Rabbis, the Hindu Temple Society of North America, the Church of Jesus Christ of Latter-day Saints, the U.S.-based Sikh Coalition, and the Greek Orthodox Archdiocese of America were all in attendance.

Last month, I wrote about a series of meetings and dinners Anthropic organized with a collection of 15 Christian leaders. Anthropic was looking for advice from the Christians, and guidance on the supposed “spiritual development” of its Claude AI model. At the time Anthropic said it was working on arranging meetings with moral thinkers who represented other groups. It’s not clear from a fresh Associated Press piece about the Faith-AI Covenant meeting whether these latest conversations with religious leaders and the earlier meetings with Christians were part of a single coherent program at Anthropic, and whether the staff members who participated in the Christian summit participated in this one as well. Gizmodo asked Anthropic for clarity about this on Saturday, but Anthropic did not return our request as of this writing.

The Associated Press also says OpenAI and Anthropic “initiated outreach,” but also that a Swiss NGO called the Interfaith Alliance for Safer Communities organized it, and has plans for future events along similar lines in China, Kenya and the United Arab Emirates. Also mentioned as a “key partner” was Baroness Joanna Shields, a member of the British House of Lords.

There’s not a single clear takeaway in the AP story—no religious instructions laid out by all these spiritual leaders. But what Anthropic calls Claude’s constitution includes a dissection of the philosophically fraught moral work Anthropic is at least trying to do by injecting morals into a machine: getting it to make the decision of a person with perfect values when there’s no way to write a rule for a situation that arises, and the consequences of making the wrong decision could be dire. This, Anthropic writes, is “centrally because we worry that our efforts to give Claude good enough ethical values will fail.” To this end, the Associated Press story extracts some quietly devastating commentary from Rumman Chowdhury, CEO of a nonprofit called Humane Intelligence: “I think a very naive take that Silicon Valley has had for a couple of years related to generative AI was that we could arrive at some sort of universal principles of ethics,” Chowdhury told the AP, adding, “They have very quickly realized that that’s just not true. That’s not real. So now they’re looking at maybe religion as a way of dealing with the ambiguity of ethically gray situations.”

They are indeed looking at maybe religion. But it’s hard to picture Anthropic coming away from these meetings converted, and inserting one set of specific religious doctrines into Claude. They’re just trying to glean high order ethical truths, and demonstrating to the world that they’ve—ostensibly—left no stone unturned in searching for them. Your mileage will vary on whether you think a machine charged with making decisions or giving important advice would, when the chips are down, be able to synthesize ideal morals thanks to meetings its creators held with administrators from some of humanity’s premier religions. It probably can’t hurt, sorta like nodding at the pre-Islamic Kaaba. But then again, only God knows for sure. #Anthropic #Added #Religions #Quest #Inject #Perfect #Morals #ClaudeArtificial intelligence,religion

You’re not seeing double: XRAI and Leion use the same manufacturer for their hardware, and the glasses weigh the same. The battery spec is also similar, with up to eight hours on the frames and another 96 hours when recharging with the case. XRAI claims its display is significantly brighter than competitors’, but I didn’t see much of a difference in day-to-day use.

The features and user experience are roughly the same, though Leion’s teleprompter feature isn’t implemented in XRAI’s app, and it doesn’t offer AI summaries of conversations. I also didn’t find XRAI’s app as user-friendly as Leion’s version, particularly when trying to switch among the admittedly exhaustive 300 language options. Only 20 of these are included without ponying up for a Pro subscription, which is sold both by the month and minute: $20/month gets you a max of 600 upgraded transcription minutes and 300 translation minutes; $40/month gets you 1,800 and 1,200 minutes, respectively. On the plus side, XRAI does have a rudimentary offline mode that works better than most. For prescription lenses, add $140 to $170.

AirCaps

AirCaps Smart Glasses

AirCaps does not make its own prescription lenses. Instead, you must purchase a pair of $39 “lens holders” and take them to an optician if you want prescription inserts. I was unable to test these with prescription lenses and ultimately had to try them out over my regular glasses, which worked well enough for short-term testing. Frames weigh a hefty 53 grams without add-on lenses; the company couldn’t tell me how much extra weight prescription lenses would add to that, but it’s safe to say these are the bulkiest and heaviest captioning glasses on the market. Despite the weight, they only carry two to four hours of battery life, with 10 or so recharges packed into the comically large case. Another option is to clip one of AirCaps’ rechargeable 13-gram Power Capsules ($79 for two) to one of the arms, which can provide 12 to 18 extra hours of juice.

The AirCaps feature list and interface make it perhaps the simplest of all these devices, with just a single button to start and stop recording. Transcriptions and translations are available for free in nine languages. For $20/month, you can add the Pro package, which offers better accuracy, access to more than 60 languages, and the option to generate AI summaries on demand (though only if recordings are long enough). As a bonus: Five hours of Pro features are free each month. Offline mode works pretty well, too. The only bad news is that these bulky frames just aren’t comfortable enough for long-term wear.

The most expensive option on the market (up to $1,399 with prescription lenses!) weighs a relatively svelte 40 grams (52 grams with lenses) and offers about four hours of battery life. There’s no charging case; the glasses must be charged directly using the included USB-connected dongle.

The glasses are extremely simple, offering transcription and translation features—with support for about 80 languages, which is impressive. I unfortunately found the prescription lenses Captify sent to be the blurriest of the bunch, making the captions comparatively hard to read. And while the device supports offline transcription, performance suffered badly when disconnected from the internet. I couldn’t get translations to work at all when offline. For $15/month, you get better accuracy and speaker differentiation, and access to AI summaries of conversations. Prescription lenses cost between $99 and $600.
