Six lenses, each with its own units.

A dimension is a small, named group of everyday measurements. Each one keeps its units, its sources and its dates, so you can always see what a score is standing on, and when it is standing on nothing at all.

Sample scores are curated demo values (0–100). No clinical rule converts these measurements into scores, and no score here says whether a measurement is healthy.

Activity

Movement

Walking shoes mid-stride on a sandstone bush track in the Blue Mountains, morning light — AI-generated scene for this concept

How much you moved across the day. Two measurements from a wrist wearable: daily steps and minutes of moderate-or-vigorous activity.

Measurements: Steps steps/day · Active minutes min/day
Source: Wrist wearable (device export)
Cadence: Daily, on days the wearable is worn
When it’s missing: Days without the wearable are gaps, never “zero steps”.

In the sample data · Malik’s daily steps, 90 days. His walking routine begins in late July.

Rest

Sleep

How long you slept, and sleep efficiency, the share of time in bed that the wearable estimated as asleep.

Measurements: Sleep duration h/night · Sleep efficiency %
Source: Wrist wearable, worn overnight
Cadence: Nightly, when worn
Worth knowing: Consumer wearables estimate sleep; they don’t measure it the way a sleep study does. Vital shows the estimate and labels its source.

In the sample data · Ava’s sleep duration. Shorter nights during an August launch, a six-day gap, then recovery.

Habits

Nutrition habits

A simple home-cooked bowl of rice, greens and tofu on a kitchen bench beside mandarins and water — AI-generated scene for this concept

Self-logged habits, deliberately simple: serves of vegetables and fruit, and water. This is a habit log, not a diet assessment, calorie count or nutritional analysis.

Measurements: Vegetable & fruit serves serves/day · Water L/day
Source: Daily habits log (self-reported)
Cadence: Daily, when logged
When it’s missing: Malik never set up the log, so his nutrition dimension is missing for the whole record and is excluded from his index.

In the sample data · Ruth’s logged serves. She stops logging on 11 September; the record simply ends.

Balance

Recovery & wellbeing

A person seated cross-legged on an exercise mat in evening lamplight, a cup of tea beside them — AI-generated scene for this concept

A device measure and a human one, side by side: overnight heart-rate variability (RMSSD) from the wearable, and a 1–5 wellbeing check-in you rate yourself.

Measurements: Heart-rate variability ms (RMSSD) · Wellbeing check-in 1–5
Sources: Wrist wearable · Wellbeing check-in (self-reported)
Cadence: Overnight when worn · most days
Worth knowing: HRV varies a lot between people and with age. Vital never compares one person’s HRV with anyone else’s.

In the sample data · Ava’s overnight HRV, which dips during her launch weeks and returns.

Measurements

Cardiovascular measurements

A home blood-pressure cuff and monitor on a timber table with a mug of tea and a notebook — AI-generated scene for this concept

Resting heart rate from the wearable, and blood pressure from a home cuff. Vital shows these as measurements with units and dates; it does not grade them, flag them or interpret them.

Measurements: Resting heart rate bpm · Blood pressure, systolic / diastolic mmHg
Sources: Wrist wearable · Home blood-pressure cuff
Cadence: Daily (heart rate) · irregular home readings (blood pressure)
Important: If a reading worries you, talk to a clinician. Vital isn’t a monitoring service and doesn’t watch for anything.

In the sample data · Malik’s home blood-pressure readings, Mondays and Thursdays, with a nine-day pause in late August.

Measurements

Metabolic measurements

A glucose meter, test strips, a plain unmarked envelope and a tape measure on a kitchen bench — AI-generated scene for this concept

Occasional fasting glucose results and waist measurements. These arrive weeks or months apart, so freshness matters more here than anywhere else.

Measurements: Fasting glucose mmol/L · Waist circumference cm
Sources: Pathology result (lab report) · Tape measure (self-measured)
Cadence: Occasional
When it’s stale: Ava’s only results are from July. At 70+ days old they fall outside the 21-day freshness window, so metabolic is excluded from her index, shown as stale, not as zero.

In the sample data · Ruth’s three waist measurements across 90 days. Sparse readings are drawn as points, joined only by a faint dashed guide.

All measurements at a glance

Thirteen measurement types across six dimensions, every one with an explicit unit and source.

What a sample score is, and isn’t

It is

A curated 0–100 value attached to each day that has evidence for that dimension.
Linked to the observations recorded that day, so you can trace it.
Part of a fictional storyline, generated alongside the measurements so they move together.

It isn’t

A clinical rating, a grade or a judgement of any measurement.
Comparable between people, or with any population norm.
Something a real product could use without agreed, validated criteria for each measurement.
