Flat screen displays are much more stable and reliable than the old displays. However, we may still look at our display and wonder whether it is accurate. Does your laptop display white at home match the white at work? Is the balance between the highlights and the shadows right? ByEye let you capture and record the appearance of colours by matching them on the phone display, with the help of the camera.
