Sickness
+ Add → Sickness.
Record that you are unwell, when it started, and roughly how badly.
Why it matters more than most
Illness moves nearly everything this app measures. Resting heart rate rises, HRV
falls, sleep fragments, temperature shifts, Capacity drops.
Without knowing you were ill, the app sees a body under load and no explanation.
With it, the same data reads correctly.
This is also directly useful to us. Part of what we are building
towards is spotting illness early from these signals — and to know whether
that works, we need cases where somebody was genuinely ill and told us so.Your logged cold is a labelled example, and labelled examples are what make the
difference between a hunch and a method we can trust.
Backdating
You can mark a start date in the past. Most people realise they are ill a day
after their data did, and the honest start date is the useful one.
Ending it
Mark when it resolves. An episode left open forever is less useful than one with
edges.
Night Log
A different thing: recording that you were awake in the night, at the time,
without properly waking up.
Turning it on
Off by default. Menu → My Profile, and toggle it on.
How it works
If you wake in the night, one tap records it. The screen is deliberately dim and
minimal — the whole design goal is that using it does not wake you further.
You can note what kind of waking it was — up for the loo, awake for no reason —
and the app closes the entry itself if you fall back asleep without saying so.
Why we would like you to try it
Your wearable infers wakings from movement and heart rate. You know whether
you were awake.
Those two frequently disagree, and the disagreement is exactly what we need. A
night your device scored as fragmented reads very differently when you know the
person was up twice with a child — and a night it scored as unbroken reads
differently when you know they lay awake for an hour.
If you sleep through
Leave it off. It is only useful if you are the kind of person who wakes and
notices, and there is no value in a feature you will never open.
