## What is Vein Finder?

REQUIRES IN-APP PURCHASE

Vein Finder uses your iPhone's camera and torch to help visualise subcutaneous veins in real time — no special hardware required.

Using published haemoglobin imaging techniques, the app processes each camera frame to highlight the contrast between vein-rich tissue and surrounding skin. Haemoglobin absorbs green light at 542 nm and 576 nm; by subtracting a scaled green channel from the red channel (R − s·G), veins stand out clearly against the background.

• Real-time 30 fps vein visualisation using R−G channel processing
• Adjustable torch with continuous brightness control
• Enhance slider to tune signal strength to your skin tone and lighting
• Contrast slider to improve visibility in varying conditions
• False-colour overlay (cyan veins on dark background) for easy tracing
• Photo capture — save processed images directly to your photo library
• Guided onboarding with technique tips for best results

Vein Finder is intended for educational and research purposes only. It is not a medical device and must not be used to guide clinical procedures, venipuncture, IV placement, or any medical intervention. Always consult a qualified healthcare professional for medical procedures.
