How to Get the
Best Reading.

01
Position Your Finger
Hold your index finger 10–15 cm from the camera. Nail bed facing the lens. Ensure the fingertip and nail are fully visible.
02
Ensure Good Lighting
Natural light or a bright room gives the most accurate colour readings. Avoid harsh shadows or direct sunlight on the finger.
03
Hold Steady & Capture
Keep your finger still, press Capture. The AI analyses nail bed colour, skin tone, capillary visibility and surface texture.
04
Receive Your Analysis
Within seconds, on-device proxies return colour and contrast signals for clinician discussion — educational CDS only.
What the AI Analyses
Nail bed colour & pallor
Nail texture & ridging
Capillary visibility
Skin tone & circulation
Nail shape & curvature
Cuticle & skin hydration

Surface anomalies
Educational CDS — not a diagnosis

AETERNO Fingerprint Intelligence is educational clinical decision support only — not a medical diagnosis and not a CE-marked medical device. Colour and capillary proxies require professional review. Always consult a licensed clinician. Emergency in the EU: 112.

The Science

What Your Finger
Reveals.

Clinical medicine has long used visual finger examination as a diagnostic aid. AETERNO applies on-device machine vision to educational colour and contrast markers — for clinician discussion, not diagnosis. Related: Blood · Biometric identity.

Nail Bed Colour
Pink nail beds often accompany healthy-looking circulation language. Pallor, cool or warm casts are educational discussion points — lighting matters. Not a haemoglobin or SpO₂ test.
Nail Shape & Ridging
Ridging, clubbing and spooning belong in clinician inspection. This module focuses on colour and contrast proxies from a still frame — shape is noted as not measured.
Capillary Patterns
Micro-contrast near the nail fold is an educational capillary-visibility proxy. Autoimmune or circulatory topics stay with a clinician — never a diagnosis here.
Skin Tone & Hydration
Tone uniformity and surface contrast hint at hydration / circulation language for discussion only. Confirm with clinical exam.
Cuticle Health
Cuticle detail needs close framing. Ragged or inflamed edges in real life → clinician review. This scan does not diagnose autoimmune disease.
Colour Symmetry
Left–right luminance difference can be shadow or true colour difference. Persistent asymmetry → clinician check. Not a Raynaud diagnosis.
