30-day index 74 · cov 5 of 6Sleep and recovery dip during an August launch; six wearable-free days; metabolic results stale.
Health information, seen as a whole sky.
Movement, sleep, nutrition habits, recovery, cardiovascular and metabolic measurements, held in one calm, navigable picture across ninety days. The maths is published, and every gap is shown honestly.
Synthetic sample data. The index is an illustrative wellness index, not a clinical score, a diagnosis or advice.

Everything on this site is synthetic. Ava, Malik and Ruth are fictional people with generated measurements. SEVN Vital is a design concept, not a medical device.
A day in the data
05:50Sleep
The night arrives as data before you do. Time asleep and sleep efficiency, estimated by a wrist wearable, land on the date they belong to.
06:40Movement
Steps and active minutes add up along the track. Leave the wearable at home and the day is recorded as a gap, never as zero steps.
17:30Nutrition habits
Two serves of greens and a glass of water, logged in a few taps. A habit log, not a diet assessment.
20:15Recovery & wellbeing
A stretch and a one-to-five check-in. Overnight heart-rate variability follows while you sleep: a human measure beside a device one.
21:30Cardiovascular & metabolic
Some measurements come rarely. A home blood-pressure reading twice a week, a pathology result months apart. Each one carries its date and its age.
NightThe whole sky
Every day folds into one constellation: six stars, ninety days, and every gap left where you can see it.
Take one number apartConcept visualisation · AI-generated scenes, no real person or home
One number, six layers deep.
Start with the index
Malik’s illustrative index for the 30 days to 28 September is 64. On its own, that number says almost nothing.
Lift it apart
Underneath sit six dimensions. Each layer carries its own sample score, its weight, where its data came from and how fresh it is.
A gap stays a gap
Malik never set up the habits log, so nutrition has no data. Its layer stays empty and the other five share its weight. Counted as zero, it would have pulled the index down to 53.
Put it back together
The index is the weighted average of the layers that have data. Coverage sits beside it, never folded into it.

Six dimensions, taken from ordinary days
Each dimension gathers a handful of everyday measurements with explicit units and sources. Its sample score is a curated 0–100 value for this demo, not a clinical rating of the measurements beneath it.

Photography-style scenes are AI-generated for this concept. They show no real person or home.
Missing is not zero.
When a dimension has no recent data, Vital leaves it out of the index and says so. Coverage falls visibly; the index doesn’t quietly drop as if you had suddenly become unwell.
Try it: switch dimensions off as if their data had never arrived. The index is recalculated from what remains, and coverage tells you how much of the picture that is.

Different lives, different gaps
The rolling 7-day index for each synthetic persona, with daily coverage beneath it. Hover or tap to read any day. Hatched bands mark days when the wearable recorded nothing.
Malik 52
30-day index 64 · cov 5 of 6A walking routine from late July lifts movement. Nutrition never logged, so it stays out of the index.
Ruth 67
30-day index 69 · cov 6 of 6Steady routines and a two-week trip without her wearable. Her habits log ends mid-September.

What Vital will never do
Vital is for understanding information, not judging it. These limits are part of the design, not the small print.
DiagnoseNo condition labels, no “abnormal” flags, no clinical interpretation of any measurement.
Predict riskNo disease-risk scores or forecasts. What-if scenarios are arithmetic on typed-in values, nothing more.
Advise treatmentNo medication changes and no treatment suggestions. It helps you prepare questions for a clinician instead.
Take real recordsThis concept accepts no real health data. Every person and number here is synthetic.
