Click on "Developer Website" or "William Lewis Website" below to see VeinSeek Pro in action! VeinSeek Pro is an augmented reality 'vein finder' application for your smartphone. ---------------------------------------- Instructions for first-time use: 1) Hold your iPhone at least 10 cm (4-5 inches) away from the skin. 2) Turn the flashlight on by pressing the flashlight icon at the bottom left of the screen. 3) Adjust the contrast with slider to the *lowest* setting that allows you to see veins well. 4) If you still can't see veins, try a physical maneuver; lower an arm vein below the level of the heart, or use a tourniquet, for example. 5) If all of the above fail, try looking at a different site. VeinSeek will not perform as well as ultrasound for deep veins. ---- Follow us on twitter: @VeinSeek ---- Read reviews on our website: www.veinseek.com Please leave us a review on the App Store!
