Your Apple Watch takes readings all day and all night: heart rate variability, resting heart rate, sleep stages, steps, workouts. Apple Health stores it all, but it rarely tells you what any of it means for today. That gap is why I built Attuno.
Your watch takes the readings. Attuno tells you what they mean. Every morning it reads your recovery, sleep, HRV and energy and hands them back as something you can act on.
One number, and the reason underneath it
Attuno scores your recovery against your own rolling 14-day baselines, not a population average, and then writes the reason in a plain sentence. A typical morning reads like this:
Two things moved. Your HRV came in at 38 ms against a 14-day baseline of 47, about 19% below what is normal for you, and you slept 6h 12m, roughly an hour and a half short of your target.
Underneath the score you see what drove it (HRV, resting heart rate and sleep, weighted and shown) and a confidence level, so you know how much data the morning had to work with. The week sits above it as seven dots, so you can tell one bad night from a pattern.

Your morning score, spent across the day
The score is redrawn as an energy charge that drains as you move, scaled to your own typical day. Today's movement target sits underneath it. On a low morning it turns into a ceiling instead of a goal, so you don't dig the hole deeper.
Ask it about your own night
The coach can see the day you're asking about: your scores, where each metric sits against your baseline, and the tags you added. So you can ask things like:
"Why is my recovery lower than yesterday?"
"Can I train hard today, or keep it easy?"
"Does drinking actually cost me anything?"
Answers come back with your own numbers in them. The AI is part of the subscription, not a second one, and it isn't metered.

How the night actually went
Sleep stages, time asleep, how settled you were and how steady your bedtime is, with heart rate plotted across the whole night. Every chart shows your typical range behind it, so a reading lands as either normal-for-you or worth a look.

The effort behind the recovery
Apple Watch workouts with pace, the heart-rate curve, time in zones and the route on a map. Six weeks of training volume and your personal records sit behind them.

What a late night actually costs you
Tag a day with alcohol, travel, a hard session or feeling under the weather. Attuno measures each tag against the mornings that followed and reports your history, not a general claim. For many people the late-night tag is the clearest pattern of all.

On your wrist
A native Apple Watch app with thirteen complications, in every face size. Every reading is drawn against your own range for the day, because a heart rate of 120 is a sprint for one person and a flight of stairs for another.
