Product description
Will the COROS Heart Rate Monitor support ANT+?
No, There will be no ANT+ support as we are using a newer Bluetooth chip which does not provide ANT+ support but has far better computing power and lower power consumption than chips with ANT+ support.
Can I pair the COROS HR Monitor with My Phone?
To record a workout with the COROS Heart Rate Monitor directly from your phone, we recommend using a free activity tracking app like Strava, MyFitnessPal, RunTracker, or others available on the iOS and Google Play stores.
Can I pair the COROS HR Monitor with My Phone?
*The COROS app currently does not support recording activities on the app itself. The COROS HR Monitor can also pair with any fitness tracking watch, gym equipment, cycling computers, and more.**
Does the COROS Heart Rate Monitor work over tattoos?
Depending on the density of the tattoo, the heart rate monitor may be able to get a reading but it’s not guaranteed. If you have tattoos, we recommend adjusting the placement (bicep, forearm, opposite arm).
How do I charge the COROS Heart Rate Monitor?
Connect the charging cable to the backside of the heart rate monitor. An orange light will appear while the monitor is charging. The light will turn green once it’s fully charged.

Don’t miss a beat!
Bottom line up front: buy this heart rate monitor, you won’t regret it.I’ve spent the last few months putting this COROS armband through its paces. As a triathlete with a CrossFit problem, here’s what keeps me coming back:1. Accuracy. First and foremost, it consistently delivers results on par with my Polar H10 (which now sits in a drawer as a result) and, in some cases, was more accurate (especially activities that sometimes involve weird chest movements or jumping, like in CrossFit). It showcases an absolutely snappy response to abrupt changes in HR during interval training. And, because it’s an optical HRM, zero issues with tracking correctly from the moment you hit start, no matter the environmental conditions (unlike the age-old problem with humidity on chest sensors).2. Comfort. It’s so light you completely forget it’s there! Importantly, it never rubs, chafes, or creates discomfort. On the upper bicep, it’s never in the way, no matter the activity. The band itself easily adjusts to any arm and it can slide right off the sensor to throw in the washing machine and clean (when was the last time you washed your chest sensor??).3. Ease of use. Frankly, it just works. If you own a COROS watch, this will sync right up. Though, while it works seamlessly with the COROS ecosystem, it will work with any Bluetooth-connected device (I have paired it with indoor rowers, other exercise machines, and non-COROS watches without problem). Lastly, this thing has a long battery life and is rechargeable, so you never have to worry about not having a spare battery on hand (the app or watch will even tell you how much battery is left).Zero regrets on this purchase. I strongly recommend the COROS armband to anyone who asks.

Must have for runners
I wish I had bought this sooner, it’s way less sporadic and the heart rate data makes much more sense than my watch data. Very easy to pair with my watch and treadmill and the battery lasts a long time. Stays put and is low impact to wear.

Awesome product!
Can’t say enough good things about this arm band HR monitor. I have a top of the line Polar H10 chest strap and there’s no comparison. I’ll NEVER go back to the chest strap!!!The chest strap isn’t comfortable and always feels like it slips down. It also randomly loses connectivity. The Coros HR armband is so comfortable you forget you’re wearing it. It’s also (most importantly) VERY accurate and doesn’t lose connection.Another very important thing to consider is the fact that the optical HR on all watches doesn’t work that well, especially for women who aren’t vascular. The optical on the watches seems to have a hard time picking up the pigment changes from the wrist. This arm band has completely solved that problem!Another thing that shouldn’t be overlooked is the simplicity and battery life. Simple because all you have to do is keep it charged and put it on. It’s all automatic. Turns on and off by itself. And one charge will last about 30 hours.There are now four people in our running group who own the Coros and everyone loves it. Coros, you knocked it out of the park with this armband technology and you deserve credit for that. Thank you and keep up the good work.P.S. – Although I own the Apex 2 and love it, the best bang for the buck at this time (01/30/24) would be to combine the Pace 3 with this armband HR monitor.

Super accurate, super comfy, very versatile!
I was a part of a voluntary COROS HRM device testing program for two months ahead of the public release for this device, and was so impressed with the metrics it provided that I felt it valuable enough to buy as a gift for a fellow athlete. This quick review reflects my experience with the device during testing (and afterwards), and is not sponsored by COROS.About me: I’ve been an avid runner since 2012, trending towards longer endurance-based events. I’ve run a number of ultramarathons and a handful of 100 mile races. I also do a bit of road and indoor (stationary trainer) cycling as cross-training.Things I like: This HRM appeals to me because of its simplicity and versatility. I like that there are no buttons (it senses when it is being worn), and I like the fact that once you set the sizing, it stays put and is easy to slip on before an activity. For sizing: I’m 5’-9”, 160-ish, and I still have plenty of slack in the strap…but I don’t do a lot of lifting. It is SO much simpler and WAY less noticeable than a chest strap. I also love the magnetic charger–even though it is relatively short (and proprietary). Charging is quick, and the battery life is ample, so it won’t be charging for very long anyhow.Data accuracy: During testing I compared this new HRM to my Wahoo TICKR HRM, as well as data from wrist-based optical HR sensors (COROS Pace 3 and Apex 2 Pro watches). The short summary is that the most consistent data came from this COROS armband. The KICKR chest strap–while plenty accurate–was slower getting an initial reading before beginning an activity, and had some data drop-outs during the activity as well. Chest straps occasionally require adjusting during activities as they loosen and slip. Wrist-based HRM sensors work fairly well, but are somewhat activity dependent. Cycling (especially if venturing off-road) can jostle these sensors from wrist contact and can result in some inconsistent data too. The armband stays securely in place, and is so comfortable and light I often don’t notice I’m wearing it. During testing there were data anomalies from all devices, but the armband HRM produced FAR FEWER than any of the others.Material thoughts: The armband material has held up well so far, but DOES tend to get stinky and discolored with wear. I’ve had mine since early July, and wash it with soap and water occasionally when I can’t stand the funk, and it cleans up nicely (see photos). Replacement armbands are also available, though I can’t see needing one for a good while.Something I wrote to the product testing group during evaluation: “The more I run with both an arm and chest strap the more I LOVE the arm band. I’ve now got a rash from the chest strap and it drops signal more than any of the three HR options. I’ll admit that I’m a sucker for simplicity, so would normally just use readout from the watch (decent)…but if I need an accurate and responsive HR readout, I’m picking the HR31.”Summary: This armband doesn’t miss a beat (ha!) and makes a lot of sense for an athlete interested in reliable HRM data across multiple sports. I initially wasn’t too keen on adding another device to my quiver, but this HRM earned its place, and would be a worthy asset to those who value consistent accurate data across disciplines.

Game changer.I’ve been using chest straps for the last 15 years. Never really any issues other than batteries dying. Gone through Garmins and then maybe 3 wahoo ones. All fine I guess, the Wahoo’s only seem to last a couple of years for some reason. Now, pre-setting the strap for these has always been just one of those things I did, either under a tap and embrace the chill when you put it on, or the spit and rub which always had a mildly kinky vibe to it 🙂 Not to mention the more often than not coffee scented strap after a while.Then I finally cave a get this little switcheroo. I wasn’t sure how good it would be using the same kind of system that watch based heart rate sensors use (which always seem to lock on to cadence for me). But this thing is solid. Comfy, requires no spit and means i can add a new weird tan line to my arm come summer.But in seriousness, it’s accurate, connects to my suunto watch, (i’ve not used the coros app), is accurate and i honestly forget I’m wearing it. Plus being that it sits on my upper arm and not at the core of my body, it doesn’t get anywhere near as sweaty in the heat.

Excellent armband heart rate monitor. It connects flawlessly to my Peloton equipment with zero setup hassle. It’s comfortable to wear, and once you’re used to having an armband HRM, you barely notice it’s there. Heart rate tracking is very accurate—especially the rise and fall during workouts—noticeably better than what I get from watches, which is exactly why I purchased it. I don’t own any other COROS products, so this has been a standalone purchase for me, and it’s performed perfectly.

Original product. Works as expected. Better HR tracking compared to wist based heart monitor. Got this to get better accuracy as far as training load is concerned. Amazing battery life and connects easily with a COROS watch via the app.
