Pros	A nurse filters the signal, so members are not sent every deviation No hardware to buy beyond the phone already in your pocket Aimed at intervention before symptoms, not diagnosis after them	Compresses a day-long diagnostic pathway to about 30 minutes Puts the scan in the hands of the clinician already with the patient CE Class IIb marking rather than research-only status
Cons	No pricing published anywhere The baseline needs weeks of consistent daily readings to mean anything Camera readings vary with lighting, skin tone and finger placement	Not FDA approved, so unavailable clinically in the United States No published pricing Guided scanning still depends on the operator's hand
