A calm look inside

Insight-first — your score, what moves it, how your energy runs through the day, and how you actually slept. Never a wall of charts.

Attuno Today screen: a Recovery score of 58 rated Moderate, the sentence explaining what drove it, the week's green-day dots, and the HRV, resting heart rate and sleep contributions
Attuno Energy today: a charge curve draining from 58% through the day, with Today's target asking for 470 to 640 kcal and 427 done so far
Attuno day tags: alcohol, late meal, late caffeine, stressful day, late night, travel, under the weather, hard session and mindfulness, each one tappable
Attuno heart rate while asleep: every reading as a dot with the trend through them, falling to a trough mid-night, with lowest 47, average 56 and highest 65 bpm
Attuno Trends screen with the weekly recap and per-metric sparklines
Attuno Activity screen: this week's workouts, a six-week training-volume chart and personal records
Attuno workout detail: a 8.06 km run at 4:43 per kilometre with its heart-rate curve and time in heart-rate zones
Attuno workout route drawn on an Apple Maps basemap, with a finish marker

On your wrist

A native Apple Watch app with watch-face complications — available now.

Attuno on Apple Watch showing a Recovery score of 74 in a green ring, with the line 'Solid recovery — a good day to push'
Attuno heart rate gauge on Apple Watch: 66 bpm in the centre of an arc running from a minimum of 48 to a maximum of 142, with resting heart rate of 54
Attuno HRV gauge on Apple Watch: 62 ms in the centre of an arc from 44 to 78, labelled 'above your usual'

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.

Your body, in plain language

Every metric, scored on-device and explained — so you know what moved, and what to do about it.

Recovery score

A single, honest read on how recovered you are today — built from your own rolling baselines, not a population average.

Insight, not just numbers

Premium AI explains why a score changed and what to try next — calm guidance, never a wall of charts.

Sleep, stress & energy

HRV, resting heart rate, sleep stages, respiratory rate, blood oxygen, steps and active energy — trended over time.

Activity & workouts

Your Apple Watch workouts with pace and a heart-rate curve — the effort behind the recovery.

What moves your recovery

Tag a day — alcohol, a late night, travel — and Attuno measures each one against the mornings that followed. Your own history, not a general claim.

Energy through the day

Your morning score, redrawn as a charge that drains as you move — scaled to your own typical day, not anyone else's.

Today's target

What today is actually asking for. On a low-recovery morning it becomes a ceiling instead of a goal.

A score for every night

Time asleep, how settled you were, and how steady your bedtime is — plus your heart rate across the night.

Trends that matter

Your typical range behind every chart, so a number reads as normal-for-you or worth a look — at a glance.

Private by design

Metrics and scores are computed and stored on your iPhone. Health data is never sold and never used for ads.
