Review: Great but you don't get to spit on you hand and rub it like you do a chest strap...... :) - 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.
Review: Works brilliantly - Brilliant product. Having had a Polar H10 for years and gone through god knows how many chest straps I decided to try this as I'd heard good reviews about arm straps. It's not missed a beat since getting it...excuse the pun! It's also less restrictive than something around your chest and a lot more accurate than the wrist based HR.

## Questions & Answers

**Q: Will the COROS Heart Rate Monitor support ANT+?**
A: 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.

**Q: Can I Pair the COROS HR Monitor with My Phone?**
A: 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.

**Q: Can I Pair the COROS HR Monitor with My Phone?**
A: *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.**

**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 back 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.

### ⭐⭐⭐⭐⭐ Great upgrade from wrist based hr.
*by J***G on 26 January 2026*

Significant upgrade vs wrist hr. A lot more comfortable than chest strap. I did an 8 x 400m interval session in sub zero weather and it record 7 out of 8 with a small error on 1. Super easy to set up on a Garmin watch.
