Huemetric

Huemetric is a color vision screening tool for anyone who wants a quick, honest answer about how they see color — built for people who suspect a red-green or blue-yellow difference, or just want to check. Every other color blindness test app shows you the same fixed set of images every time, which means the answers can be memorized after a repeat or two. Huemetric generates a brand-new set of pseudoisochromatic plates on the fly for every single screening — different dot mosaic, different digit, different session — so there's nothing to memorize and nothing stale to look at. The Quick Screening takes about a minute: read 10 plates, answer with the number pad, and get a clear result — normal color vision, or signs of a red-green or blue-yellow difference. No color-coded verdicts either: since this is a color vision test, results are always shown with icons and text, never by relying on hue alone. Huemetric runs entirely on your device: no account, no sign-in, no cloud sync, no ads, and no data collection of any kind. Included: unlimited Quick Screenings, fresh plates every time, and your most recent result. Huemetric Pro is a one-time unlock for the full 24-plate clinical screening protocol, a detailed severity breakdown per axis, and unlimited on-device screening history with trend over time. Huemetric is a screening tool, not a medical diagnosis. If you have concerns about your color vision, consult an eye care professional.
