Paired easily with my Coros Dura, and is very accurate. Arm strap is easily adjustable and comfortable, and it works as a designed. I wish it had a power switch, but I’ll easily trade that for the ability to recharge! Review: Works great with ZonePoints app - This is a nice heart rate monitor. I use it while riding a stationary bike. It is simple to use, comfortable, accurate, and reliable. The tricky part was finding a decent app to interface with it. The COROS app isn't all that useful during workouts. It will show your current heart rate and that's about it. In my opinion, the popular exercise apps like Strava and others ask for too much personal information upfront and are cluttered with too many functions that I don't need. Plus they tend to prod the user to sign up for a monthly subscription to "unlock premium features." The best app I've found is ZonePoints (Android). It works well with this COROS HRM and it shows a real-time graph of heart rate, color-coded for 5 different zones. It also saves each workout to history and stats for comparison. ## Features - COROS Heart Rate Monitor armband is designed for measuring heart rate during sports and activities.

The COROS HR Monitor can also pair with any fitness tracking watch, gym equipment, cycling computers, and more.** **Q: Does the COROS Heart Rate Monitor work over tattoos?** A: 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). **Q: How do I charge the COROS Heart Rate Monitor?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Heart Rate monitor! *by V***T on March 30, 2026* Outstanding rechargeable Heart Rate Monitor.

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. ## Frequently Bought Together - COROS Heart Rate Monitor, Comfort, Easy to wear, Auto-wear Detection, Advanced Sensor, Precise Data, Bluetooth, 38 Hours Battery Life, Connects up to 3 Devices at Once, for Run and Bike - COROS PACE 3 Sport Watch GPS, Lightweight and Comfort, 17 Days Battery Life, Dual-Frequency GPS, Heart Rate, Navigation, Sleep Track, Training Plan, Run, Bike, and Ski (Black Silicone) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/623376394-heart-rate-monitor-comfort-easy-to-wear-auto-wear-detection](https://www.desertcart.vu/products/623376394-heart-rate-monitor-comfort-easy-to-wear-auto-wear-detection) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-09*
