Polar Reviews 661

I am writing this to share my deep frustration with the new Polar Grit X2 Pro. Despite being a premium sports watch, it is virtually impossible to synchronize it with my phone.

I have spent the entire day trying to fix this: I've reinstalled the Polar Flow app multiple times, restarted both the watch and the phone, and ensured all software and firmware versions are up to date. Nothing works. From a device of this price point, I expected a 'plug and play' experience, but instead, I got a constant struggle with connectivity.

It's disappointing to see such basic

functionality failing on a flagship model. I hope Polar addresses these sync bugs immediately, as the watch is currently useless without data synchronization

Polar is one of the worse companies to buy from when it comes to health gadgets in my opinion. Polar H10 is annoying to use and terribly designed. For example Polar H10 measures live HRV but doesn't show it. It literally refuses to allow the user to see the live HRV data. According to online forums downloading additional 3rd party apps is needed to actually see the live HRV data. I bought this device only to track live HRV. It does track it but will not show it unless I download apps that aren't even owned by Polar. Beyond ridiculous.

Polar what an utter awful experience. Avoid the Polar H10 chest strap heart rate monitor. Customer experience is awful. Numerous emails trying to sort out issues to no avail. Eventually finding out Strap less than 3 months old needs replacing and NOT under warranty. DO NOT WASTE YOUR £70+ AVOID

As a first-time visitor, this completely killed my interest in Polar.

The website is extremely slow, and the comparison page simply doesn’t work properly. For a brand that sells modern fitness tech, this is honestly surprising and disappointing.

If a company can’t maintain a basic website experience in 2026, it raises serious doubts about how well their apps and overall ecosystem are handled.

I came here ready to explore and potentially buy, but left frustrated instead. First impressions matter — and this one was not good.

Polar Vantage M3 has a barometric sensor but POLAR has DISABLED usage for EXTERNAL TEMPERATURE MEASUREMENT in its software. Either you are incapable of software development or even worse decided to promote the more expensive model Vantage V3. The lame excuse that temperature measurements are biased by body temperature is a joke. Barometric sensors are all able to measure temperature. Even with my Polar S720i you could measure temperature with a barometric sensor at similar position very well even while swimming. Don’t allow your marketing annoy loyal customers and destroy your high quality brand. Chinese competition is very well on its way.

Premium price, substandard durability, and worse customer support

I rarely write reviews like this, but this experience warrants it.

I purchased a Polar device expecting a durable, high-quality product consistent with its premium positioning. Instead, the device failed just a few months after the 2-year warranty period—well short of any reasonable lifespan for this category.

What’s more concerning is that even Polar’s own support acknowledged that this type of failure is “bizarre” and that their devices are expected to last well beyond two years. Despite that, they refused to stand behind the product in any meaningful way.

Their solution? A 50% discount to buy another device.

Let’s be clear: that is not a resolution. That is asking the customer to pay again for a product that has already demonstrated poor reliability.

The issue here is not the warranty policy—it’s the complete lack of accountability for premature product failure. Drawing an arbitrary line between “a few days” and “a few months” past warranty does not change the fact that the product did not last as it should have.

For comparison, competing devices—particularly from Garmin—routinely last 4–5+ years under similar use. That is the standard in this space, and Polar falls short.

Equally disappointing was the customer service experience. After weeks of back-and-forth, escalation attempts, and clear documentation of the issue, the company remained rigid and unwilling to offer even a basic goodwill repair or replacement.

At that point, it becomes clear: this is not just a product issue, it’s a company policy issue.

If you are deciding between Polar and its competitors, understand this:
• The product may not last as expected
• And if it doesn’t, you will be on your own

I will not be purchasing from Polar again.

I have bought the wristband from Polar and the sleep tracking was so off. I slept for hours, then I was awake for three or four and went back to two or three. It just showed that I slept for five hours. I had to say that even after one night, I thought this is useless and it was way too expensive. I returned the product and have since four months been waiting for the money to be refunded. I tried to work with the customer service saying that if they would share an MDS, I could use a cheaper shipping method. Customer service didn't reply. The return process is extremely cumbersome and it's not customer friendly. Product quality was not good. I don't understand since in the past they had at least great reviews, but the overall review quality have one star I can agree.

I have user whoop and changed (after 18 months) to polar loop. Despite the bad advertising it works very well for a fraction of the price.

The Polar Loop is a hit! for a while now i have been using it and it's all i need! i have tried the H10, and i love it, but putting the strap and each time and maintaining it moist is a hassle for me.
i also don't like smart watches, therefore the Loop fits exactly my need, I put it on my biceps though, and all it takes is wear it once, and i forget it exists, and by the end of the day I see my progress, absolute magic!

Absolutely appalling customer service. I've sent multiple emails to their Australian sales team to buy a watch and haven't had a single reply in 12 days. Is there a human working there?" Their whole office needs to be "restructured"

*** buyer beware ****
I would give it zero stars! Worst customer service. I purchased a watch and charger, because the charger isn’t included. When my father tried it on he didn’t want it. I went to return and was told I am responsible for the shipping and would be able to get a 10$credit. I feel like after spending 140$ I should be able to return something if the person I was gifting it to didn’t want it.
I’m disappointed and will not recommend a company that does not allow returns. What a terrible policy.

Hr monitor connects to machines but dosnt connect to its own apps 😂. Can’t reset password - dosnt send 😅. Customer support? Non existent help

Today, I gave up on my Polar Loop journey.

I was immediately drawn to the concept behind Loop: a screenless wearable focused on simplicity, paired with a one-time purchase model instead of a subscription. Coming from a very positive experience with Whoop, I was eager to find a comparable alternative without committing to a recurring fee. I’ve never been a fan of subscription-based hardware, so Polar Loop felt like the perfect solution.

I purchased it in October 2025. Unfortunately, the first signs of trouble appeared almost immediately. The user interface felt unintuitive, and the software showed clear signs of instability and bugs. Still, I decided to stick with it. I genuinely wanted it to improve. I waited for updates, hoping that the rough edges would be smoothed out and that the platform would mature.

They didn’t.

Today, I gave up on Polar Loop because the software is simply not suitable for an average user — someone who wants accessible health insights and practical guidance to improve their physical condition.

The Core Problems
1. Almost No Proactive Insights

For a health wearable in 2026, the lack of proactive insights is astonishing. The app collects data, but rarely translates it into meaningful, actionable feedback. There’s no real sense of guidance, no intelligent nudges, no contextual analysis that helps you understand what to improve or how to adjust your habits. Data without interpretation is just noise — and Loop delivers far too much noise.

2. Strength Training Detection Is Essentially Nonexistent

Automatic strength workout detection is, in practice, absent. I have been manually tracking my strength sessions for months. In an era where even mid-tier devices can recognize different activity types with reasonable accuracy, this feels like a major regression. Manual tracking in 2026 should be an exception, not the norm.

3. Inconsistent Wake-Up Detection

The automatic wake-up detection feels random. Some mornings, you open the app and get a satisfying confirmation prompt asking whether you’ve woken up. Other days, nothing. No prompt, no acknowledgment. The inconsistency undermines trust in the system. When you can’t rely on basic features to behave predictably, the entire experience suffers.

4. Unacceptable Sync Issues

What I find particularly unacceptable is the unreliable synchronization. There are days when, despite having the app open, I see “Last sync: 23 hours ago.” I use iOS — but frankly, I don’t care whose “fault” it is. If I purchase a device, I expect the manufacturer to ensure seamless integration with major operating systems. I don’t want to blame Apple, Android, or anyone else. As a customer, I want things to just work.

An Outdated Interface
The interface feels confusing and, honestly, outdated for 2026. It looks and behaves like software from a previous era. Navigation is not intuitive, information hierarchy is weak, and the overall visual design feels old-school in the worst possible way. A health app should feel clean, modern, and empowering. Loop feels cluttered and behind the times.

Constructive Feedback
There is potential here. One feature that would significantly elevate the experience is integrated journaling with intelligent insights derived from it. Allow users to log mood, stress, nutrition, or subjective recovery — and then correlate that data with physiological metrics. That would create depth, personalization, and genuine value.

Right now, the device feels data-heavy but insight-light.

Final Verdict
For me — an average user looking for clear health information and practical ways to improve — Polar Loop has proven to be the wrong device. The hardware concept is compelling, and the non-subscription model is attractive, but the software experience ultimately determines the value of a wearable.

And in this case, the software simply isn’t good enough.

I wanted to like it. I gave it months. But today, I’m moving on.

This watch is a piece of crap!
No support whatsoever, no return address, no phone number to actually talk to someone.
I asked to return watch and they offered me $10to keep it.
STAY AWAY!!!

This is a terrible product. Do not waste your money! It doesn’t log my exercise (sometimes claiming I’ve done non when I have been exercising for 2 hrs). It constantly unsyncs from my phone, the only way to resync is by doing a factory reset (every week), which then loses all the data. And it needs to be charged every 2 days.

Polar used to be renowned for excellent quality. I myself had a V800 watch and an H7 heart rate monitor that both performed flawlessly for many years. The H7 heart rate strap just recently went dead after ten years of lifetime -during seven of which it was used very regularly (>5 times a week on average).
Due to required ANT+ connectivity and my excellent previous experience, I also fetched a more recent H10 heart rate monitor. Sadly the strap started giving erroneous and completely implausible heart rate values after a little over a year. The strap was replaced under warranty but failed again in the same manner about a year later. I am aware that in the EU, the strap's warranty period starts anew when replaced under warranty. Polar however demanded I pay 66€ for a new strap, shipping and handling, refusing warranty replacement due to the original purchase having taken place three months more than two years before. I refused, citing active legal warranty and now haven't heard from them for over a week. It's been over a month since I opened the case. So yeah, no way I'd recommend that anyone I remotely like buy a recent product from Polar.

ps.: "We're currently experiencing an extraordinary amount of requests and you might therefore experience a delay" is obviously utter bs, it was like that the last time and you can read stories like this everywhere. They might not get so many warranty cases, had they not decided to start selling crap.

Polar is ok, but hasn't kept up with the technology advancements like Garmin. I have the Polar Pace Pro. Firstly every few months you have to factory reset your watch because it stop synchronising wit the app for no reason. No matter what you do, it always ends up having to be reset. The swimming functionality is poor. The synch with Strava is faulty so indoor swimming logs my times at snail pace and open water like I am an Olympic swimmer. Cannot wait to move to Garmin!

worst fing support of all time doesnt respond

This is the WORST watch I ever bought!!! It stopped sync with my phone in less than 6 months and never sync again. I tried the support and only got automatic answers. And now, just a few months later, the battery is gone, it lasts for less than 2 hours. The watch is not even tracking my heart rate well. Less than 1 year ? Garbage...

I have to be honest I'm shocked at reviews for this company. My first Polar watch, a Polar Eclipse was purchased 5 or more years ago. It's been better than I could have expected. Reliable, long lasting & works very well for me, not a die-hard data fan but committed to regular & accurate activity monitoring.

If there's a weakness it's the Polar Flow app. When I acquired the watch is was not particularly user friendly. Whilst they've added functionality since, in all honesty it's made the app even more clumsy!

Anyway if customer loyalty is the best commitment to a product, then I should add I've just replaced my last watch with a new Polarr
