Is there a no-nonsense device that lets me measure my heart rate?


I would like to measure my heart rate and download the data to my laptop so I can do my own statistics on it.

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?

I have not tried myself, but maybe Polar H10 strap or older H7. I didn't realize that H10 works with free app, so I bought expensive HRM too. :( The strap has internal memory that can train one session of data.

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.

Your best option is a Garmin ForeRunner and the USB cable it comes with.

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.
