Description
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
