Scan results

What a scan produces, field by field, with units. You get this as a ScanResult on the device (from startScan), and — if results delivery is on — as the same fields in JSON at your backend.

Measurements

Field	Unit	Notes
`bodyFatPercent`	%	Always present
`bmi`	kg/m²	Optional
`leanMuscleMassKg`	kg	Optional
`boneMineralContentKg`	kg	Optional
`duration`	seconds	Capture time; optional

Girths

Field	Unit
`neckCm`	cm
`waistCm`	cm (natural waist)
`lowerWaistCm`	cm (belly / lower waist)
`hipCm`	cm

Advanced indicators

Field	Unit	Notes
`waistHipRatio`	ratio
`waistHeightRatio`	ratio
`centralAdiposityIndex`	index
`fatMassIndex`	kg/m²
`skeletalMuscleIndex`	kg/m²	Optional
`musclePreservationIndex`	%	Optional; needs prior scans

The whole shape

Optional fields may be absent (null in JSON, nil in Swift). The point cloud stays on the device — it is never in the delivered payload.
