VeinFinder – Explore Veins with Your Android Camera

See veins in real time with your Android camera. VeinFinder uses GPU-accelerated image processing to enhance visibility instantly, no extra hardware required. Perfect for education, skills practice, and exploration.

Key Features:
• Filter toggle (On/Off): Compare raw and enhanced vein views instantly
• Gain/contrast controls: Adjust visibility across skin tones and lighting
• Flashlight integration: Improve consistency in low lighting environments
• Secure, on-device processing: Images never leave your phone - no uploads or accounts

Best Results:
• Use soft, even lighting and avoid glare
• Hold the camera 10–20 cm from skin, steady and focused
• Choose smooth, hair-free areas such as the forearm or wrist for more clear vein visuals
• Performance varies depending on device, skin tone, and lighting conditions

Notes on Performance:
VeinFinder is optimized for Samsung devices, but works across most Android models. Ongoing updates continue to improve performance on all devices. If VeinFinder doesn’t meet your expectations, please request a refund within 2 hours of purchase.

Privacy & Safety:
• All processing happens locally on your device—VeinFinder never collects or transmits data.
• Educational use only: VeinFinder is not a medical device and must not be used for diagnosis, treatment, or clinical decision-making.
