Step into the world as millions of people experience it. See how red-green confusion, blue-yellow shifts, and full monochromacy reshape every color around you.
Using on-device AI, watch text transform the way it does for people with dyslexia. Eleven subtypes across 39 languages, all processed privately on your phone.
See the world through 10 different species. From a dog's dichromatic palette to a mantis shrimp's 12-channel spectral system to a snake's infrared thermoreception.
Privacy-first.
