Mick in PA –
I just got this yesterday. I set it up using heartool app on my iphone (this is the app recommended by COOSPO) and everything worked right away.
I’m 75 years old so the rough estimate of max heart rate would be 145. In my youth I was a good runner with a good VO2 uptake so I could usually exceed my theoretical max, so I would even agree my max might go as high as 160.
I first looked at my phone at the 10 minute mark of my first workout with the COOSPO today and the app said my pulse was 172! I slowed down (didn’t think I was working that hard) and finished the workout. When I looked at the summary it said my max heart rate during the workout was 193! So now I have to say it’s not accurate. But I’m not going to give up on it. I’ll try it for a week or two and if it improves, I’ll update my posting. The app is just a receiving tool, the COOSPO does the pulse monitoring, so I assign this result to the device, not the app.
I had the max bpm warning set for 145 but never got a warning vibration that I could feel but that might be due to the heartool app. And for those that are wondering why I didn’t see the dark red LED, I was running in 30 degree weather so the COOSPO was under the clothing.
I will add that I wore the monitor on the inside of my upper left arm. I’m going to vary between inside upper arm and outside upper arm, and forearm. Maybe one of those positions will make a difference. I’m also going to try to wear it outside my jacket sleeve tomorrow to see if it will still pick up my pulse; that way I can see the LED.
I really like the device. Simple, comfortable, easy to set up. I really want this to work.
Follow up: I wore the COOSPO on my forearm today and ran at a slightly slower pace and the device worked perfectly. I did one section where I ran hard enough to force my pulse over the alarm limit and the monitor buzzed 3 times and it was very obvious. My max pulse was 147 and I didn’t push any harder so I don’t know if it would have gone higher, but for this workout, the COOSPO did everything perfectly
Second follow up. I’ve already been contacted by COOSPO offering a refund at first and then again contacting me after my follow up hoping I would continue to be satisfied. Very happy with their communications. I’ve added a star 🙂
I’m taking the star back off unfortunately. The device freaked out again this week. I bought a Polar chest monitor to make sure I had good data so I’ve been wearing both for a few days now. A couple days ago the COOSPO alarm went off a few minutes into the run and it said my pulse was 160. The Polar said my pulse was 119 and I knew from experience and feel that the Polar was correct. I doubt my heart is capable of a pulse of 160. I’ll probably ask to return the COOSPO now which is unfortunate. It’s very easy to use and I like the alarm.

I’d been using the Polar H10 chest HRM since August 2022. It worked fine for the most part, other than a few instances of the battery compartment being wonky and giving inconsistent readings until I fiddled with the flexible contact inside.
Well, it finally annoyed me for good recently when it started to freeze on a BPM for several seconds before dropping/rising immediately. It would do this every few seconds and my BPM readings were always wildly off. I tried everything I could think of to remedy this and figured, after reading tons of similar stories online, it was best to just move on finally and buy something new.
I grabbed the COOSPO HW9 Optical HRM and have been using this with zero issues so far. Since it uses optical sensors (like a smart watch), there’s no need to wet it first or apply electrode gel. You simply place it around your forearm or your upper arm (bicep).
It has its own app but I prefer using the Polar Beat app so I can see the nice colorized graph in real time. That’s what’s cool about the COOSPO HW9, it connects to pretty much any HRM app (including PULSOID if you want to show your HR while streaming online). All I had to do was turn it on, go into Polar Beat, remove the Polar H10 from my paired devices list, and the COOSPO HW9 immediately showed up and I was able to pair it right away.
In order to test the accuracy of it, I have used it in conjunction with the continuous HRM feature of my Galaxy Watch 4 as well as testing it by comparing my heart rate with my Galaxy S10+’s HR measuring feature and the COOSPO has been spot-on for me.
A cool feature this thing has is that it has an indicator light on it that changes color based on which BPM range you’re currently in. It’s especially helpful once your heart reaches 180bpm because the light turns red and the armband vibrates a couple times. That’s been helpful when I play because it reminds me to focus on breathing and calming down during whatever song I’m playing that has my heart rate getting so high. If you use the Heartool app, you can change the HR alert value to something other than 180bpm.
Anyway, just wanted to give this thing a shoutout for anyone looking for their first HRM, a replacement, or an alternative to a chest HRM. This one is pretty comfy to wear, far better than the Polar H10 to me (which would bunch up on my sides and back). I also like that it has an internal battery that you charge with a magnetic charger (it’s recommended to charge it by connecting it to a laptop/computer or DC 5V power adapter).

Despues de un mes de uso el equipo dejo de funcionar, al principio todo trabajba perfecto sin embargo despues de mi primer salida en ruta larga (6 horas), el equipo se apago, en un principio pense que se trataba de un caso de descarga de la bateria. Llegue a casa y cargué el equipo sin embargo al encenderlo de nuevo el equipo ya no funciono, el dispositivo enciende pero ya no hace la medicion de FC.
Por ahora me encuentro tratando de aplicar la garantia del mismo

It’s very simple to use, yet has interesting elaborate color and buzz zone features.
Great conectivity, and accuracy.
After two years, I’d like the battery to be 2x or 3x more long lasting, it has not shortened over time, it’s always been a little short, charge twice a week, or more before long rides to avoid running out, I wish wahoo could display the battery level, to be fair strava and coospo app does display charge level (4 or 5sticks), 40 or 60hr battery would be a good update.
The color zone feature and 180bpm vibrating alert felt gimicky to me at first, I wanted to turn it off, you can’t, once you get used to it this is a handy features, it’s actually really good, it’s not in the way of other apps and computers.
The charger cord could be stonger, the strap is light but fairly durable if you are gentle on it. For Cycling anything light is a plus.
I usually put it on the inside of the upper biceps where it gets the best reading,
A few times (in winter when forgoten before layering up ) I’ve used it successfully on the thigh shoved in the cycling bibs or cross-country sky tights, strap left open.
At some point it stopped charging, the coospo support told me to clean the contacts, they looked clean, thin salt buildup of dust can affect it, nothing a well deserved little water and soap couldn’t fix.

Solo funciono 2 veces y dejo de cargar. He tenido otros de este tipo de precio similar y se sienten de mucha mejor clidad. Una gran decepción.

Charging is easy, works great, not complicated. Low cost alternative to name brands.

I got this since it is much easier to put on than a chest strap.
The changing color of the lights is a nice feature.
Seems to be more accurate than a wrist watch, but hard to move it from my forearm to my bicep to help with the accuracy.
Had to reconnect a couple of times with app. But tried multiple devices at once and it worked.
Convenient and does the job.

I bike and walk everyday. As I get older and wiser I needed to make sure I was properly zone training so that I don’t get injured. This HR monitor is simple and is accurate, I compared it to my Apple Watch and to a chest monitor and it is the same. Bluetooth works with my Apple Watch so I don’t need to pair to my phone, but you can pair it to your phone. I also pair this to my computer for Zwift and works amazing. I have had it for a month and it’s still holding its charge. I like the way it looks and it’s easier to put on with all my gear on, I don’t have to remove clothes to put on the monitor unlike my chest monitor which used watch batteries. The rechargeable battery is a huge advantage so that I don’t have to swap batteries ever.
