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

The Science

What Your Finger
Reveals.

Clinical medicine has long used visual finger examination as a diagnostic aid. AETERNO AI applies machine vision to these same established clinical markers — at scale, instantly, from your smartphone camera.

🩷
Nail Bed Colour
Pink nail beds indicate healthy circulation. Pallor may signal anaemia or low haemoglobin. Blue tones can indicate oxygen saturation concerns. Yellow may suggest liver or fungal signals.
📏
Nail Shape & Ridging
Longitudinal ridges are often associated with nutritional deficiencies (iron, zinc, B12). Clubbing can indicate respiratory or cardiovascular conditions. Spooning may suggest iron deficiency anaemia.
🌡️
Capillary Patterns
Visible capillaries and micro-vascular patterns around the nail fold can signal autoimmune, inflammatory or circulatory conditions. Their visibility, density and regularity all carry clinical significance.
🔬
Skin Tone & Hydration
Skin colour uniformity, dryness, and texture around the finger provide indicators of metabolic health, thyroid function, hydration status and inflammatory markers.
💧
Cuticle Health
Cuticle condition, ragged edges, and peeling skin around the nail can indicate nutritional deficiencies, inflammatory conditions, or autoimmune signals such as lupus erythematosus.
🎨
Colour Symmetry
Asymmetry in colour between fingers or zones within the nail bed can indicate localised circulatory issues, nerve compression, or Raynaud's phenomenon — all flagged by AI analysis.
