I don't want something that pairs with my phone, needs me to install software or to become member of some cloud service.
Is there something like that?

Polar H10 is very accurate. I personally pair it with free PolarBeat app (I also have the Polar HRM) and download raw data.

>The export raw data function exports second-by-second data from a training session. Raw data export gives you a zip file with player specific folders which contain a CSV file, and a .txt file and a GPX file.
> The CSV file contains second by second information about heart rate, speed, distance, acceleration/deceleration and running cadence.
>The .txt file contains unfiltered RR interval data that can be analyzed with third party heart rate variability tools.
>The GPX file contains location information that can viewed in third party tools.
I find it surprising that a we still need a chest belt to measure heart beats. I can put a finger on my wrist and feel every beat perfectly. Strange that a wrist band cannot do the same.
The chest band is still more accurate (and cheaper). It gets the minor variations in HR from beat to beat. When you get closer to your maximum HR your hard beat gets more even. HR variability gives more info.
Right, but probably only when you're stationary. Try taking your own probably when you're walking or typing.
If you’re a stickler about getting the best HRM results then get one with a chest strap but the wrist-based HRM is great for most cases.
- live data at your wrist, streamed to your phone over Bluetooth.
- A chart for the past 4 hours on your wrist.
- Longer charts with zones, averages etc on the app.
- Abnormal heart-rate warning on the watch.
- Export all data via USB to your computer.
Edit: I also got a companion HRM chest-strap (which is more precise and also provides more data related to running), but I only use it for more intense runs/training its not super comfortable.
Yes, it's less accurate than a chest strap, but it works fine for 99.999% of what pretty much anyone wants to do with it. Assuming you don't have mutant wrists, for best results, make sure the strap in snug, but not too snug, against your wrist.
And wrist-based HRM has improved quite a bit in recent years.
