Evolving Nunc

Every so often, I say to my partner: "you know, I don't know what I'll do next with Nunc, I think it's good." This usually means I have a new idea, I just haven't realised it yet.

When on holiday recently, I was chatting with a medica about the relative merits of overnight metric tracking, and I made the observation that I can't remember the last time I saw medicæ with a Whoop or Ōura. My suspicion is that they know that tracking these metrics is mostly pointless, and fills the pockets of the vendor. I won't say she exactly confirmed that, but, it felt rather close to the mark. (Chat on the one-lead ECG offered by modern wearables went the same way.)

She challenged me to re-write Nunc, so that instead of waking to a busy screen of metrics, I wake to a question: how do I feel today, compared to yesterday? (Or, at least, that's how I remember it.)

Continuing from my theme of not wanting the machine - initially someone else's machine - to tell me how I feel, this forces me to abandon my machine telling me how I feel, and actually think about how I feel, myself. (My therapist would probably be very proud.)

The new morning flow is as follows:

1. Tap to confirm sleep window.
2. Quo modo te habes?
3. ECG (continuing the optical- versus ECG-derived HRV for overnight recovery experiment)
4. Finally see my beloved Vigor Vitæ.

By default, I never see the last seven night's graph, either: I now have an algo that considers my rolling trend, and alerts me if there's a deviation.

Here we see my HRV has been decaying for the last 4 nights. The concept that I'm building towards is only experiencing signal - in this case a drop in my HRV trend - and not wasting my life looking at lines.

The result is my graph of how I'm feeling: peius, idem, or melius? In terms of data, we're at 9 noctes nights, but as the field grows, I'm looking forward to long-term analysis of the following:

1. Does how I feel in the morning track with how the data says I am?
2. Which correlates better with my perceived state, optical, or ECG?

Obviously if there's significant divergence between the data and the experience, either the data is poorly processed, or, I can stop this metric tracking game... (Obviously the former, thank you, autism.)
