OcuScreen vs DaltoTest

OcuScreen is a simple way to keep an eye on your vision and the look of your eyes, right from your iPhone. Eleven short self-guided checks cover the basics: how clearly you see up close and at a distance, whether colours look right, whether your eyes track together, how your pupils and eyelids look, and more. Each check takes a minute or two and gives you a plain green, orange or red result with a clear next step — never a diagnosis. HOW IT WORKS Pick a check, follow the on-screen steps, and get your result immediately. Four checks — sight clarity, near vision, contrast sensitivity and dry-eye signs — are free to try once each. Three checks let you answer out loud instead of tapping, recognised entirely on your iPhone. TRACK CHANGES OVER TIME Every result is saved on your iPhone so you can look back, compare, and notice changes between visits to an eye-care professional. FIND EYE CARE NEARBY A built-in map helps you find eye care close to you — always free, no credits needed. CREDITS AND PRICING After your free tries, checks use credits — most cost 1, a few longer ones cost 2. Buy a credit pack sized for one, two or three full rounds of every check, with a better price per credit the bigger the pack. Or buy the lifetime unlock once and never think about credits again — a single one-time payment, no subscription, ever. PRIVATE BY DESIGN Your photos and results stay on your iPhone. OcuScreen reads nothing from Apple Health, tracks nothing, and shows no ads. OcuScreen is a wellness and screening tool. It is not a medical device. It has not been reviewed or cleared by the FDA, the EU MDR system, or any other medical regulator. It does not replace an eye doctor.

DaltoTest screens color vision wherever you are, with five methods inspired by ophthalmology: no appointment, no specialized equipment, no account to create. FIVE METHODS • Ishihara plates: numbers hidden in colored dots, red-green screening • Farnsworth D-15: arrange 15 caps in a gradient, blue-yellow coverage • Extended FM-100 test: 96 caps in 4 rows, more sensitive to mild deficiencies • Lantern test: identify brief signal lights, professional-qualification style • Test inspired by the Cambridge Colour Test: spot a ring hidden in a dot mosaic Wondering about your color vision? It happens: you wonder if you really see red and green the way everyone else does, or if your kid keeps mixing up colors at school. DaltoTest lets you check in a few minutes, wherever you are, no appointment needed. PRIVATE BY DESIGN • All data stays on your device • No account, no server, no sync • No data is ever sent anywhere • No analytics or advertising tracking tools DaltoTest is not a medical device. This is a screening tool, for informational purposes only. It does not replace an examination by a healthcare professional. If in doubt about a result, consult an ophthalmologist.
