Silky's watch 🐯

The watch saves everything as it happens and sends it to the box in batches: straight away when she taps a button, wakes up, answers a nudge, charges or leaves home, and otherwise about every 15 minutes (slower while the watch dozes). So "right now" means "as of the last check-in", and the chip at the top says how long ago that was. The page updates by itself when a new batch arrives.

Taps are the ate, drank and meds buttons on her watch face. Nudges are the watch gently asking: water every few hours, lunch, meds with food, "put me back on", "I'm charged". They get a little more insistent until she answers (a buzz, then the screen, then chirps), and there's never any punishment. The time it took is shown so you can see how the day is going, not as a score.

About every 75 minutes while she sleeps, the watch listens closely to her heart for two minutes, with a black screen so it doesn't wake her. Each listen gives a heart rate, an HRV number and her skin temperature. "Clean beats" is how many heartbeats it could measure precisely; a listen with none gives no HRV.

The tiny differences in time between one heartbeat and the next, in milliseconds. A rested, relaxed body tends to vary more, so a higher number is usually calmer. It's very personal and jumps around from night to night, so only her own trend means anything. That's why the watch spends her first 14 nights learning what's normal for her before it compares anything.

The temperature of the skin under the watch, which is cooler than body temperature (30 to 35 °C is normal for a wrist at night, and it drifts as the room and the covers change). A rise of about half a degree above her own normal for a couple of nights can show up before a cold does.

Once she's been asleep for half an hour after midnight, the watch goes quiet: no nudges, and the buttons don't respond, so nothing gets tapped in her sleep. It ends when she holds "I'm awake~" on the watch, or by itself once she's clearly up.

A light sensor on the back notices when it's taken off, and a heartbeat confirms when it's back on. Charging counts separately. "Out" means away from the home Wi-Fi for at least 10 minutes.

Beats per minute. For most adults, resting is somewhere between 55 and 85. It goes up when she moves, laughs, has coffee or feels stressed, and down when she sleeps. A high number while she's been sitting still for a while can mean a hard moment, so it's a good cue to check in gently, not a diagnosis.

She charges first thing in the morning, and the watch nudges her when it's full so it goes back on her wrist. A steep drop means the watch was working hard (lots of screen time, or work on its software).

At Silky's own request, the watch is a little walled garden: just her watch face, her buttons and Halcyon's care. When she tries to open settings, the app drawer or the power menu, it closes again under a soft curtain with a fond word ("silly pony~"). Pushing against it is part of the play, not a problem. Pausing the watch opens the garden.
