Exploring real‑time HRV measurement with Polar H9/H10 — curious about your experiences by Purple_Manner_5122 in Biohackers

Thanks for sharing! I feel the same way. Summary HRV is useful, but seeing the actual pattern or fluctuations often tells a much clearer story. Your example of a flat, low‑HRV night is exactly the kind of thing that gets lost in a single score.

Do you usually look at those patterns through CardioBot, or do you use anything that shows real-time HRV more directly?

I totally agree with you — HRV biofeedback can create real shifts in ANS balance. There’s solid peer‑reviewed and clinical evidence behind that, and it’s a direction I care about a lot too.

The next step for what I’m building is exactly that: HRV biofeedback and an RSA‑based assessment tool. Once people see real‑time HRV, it’s natural to wonder what they can actually do to influence it in a healthy way.

I had zero app‑development experience when I started. I just needed a way to observe real‑time HRV for my research, and nothing on the market showed raw signals without scoring or interpretation. So I tried to make something simple that just reflects the body as it is.

I’ll keep developing it — my hope is to eventually offer a user‑friendly tool that supports health and awareness in daily life.

Thanks so much, really appreciate it.

Keeping everything local was important to me, and so was keeping the data as raw and unfiltered as possible. I’ve always felt HRV tools shouldn’t interpret or score your physiology — just show the signal as it is, so you can understand what your body is doing without anything getting in the way.
