Colour vision screening, one QR code away.

ColourCheck is a short, mobile-first colour vision screener anyone can take from a link or QR code handed out by your practice. It rates the outcome honestly — and when a result looks suspicious, it sends the person to exactly one place: your chair, for a full assessment.

How it works

From a poster on your wall to a booking in your diary

You share the linkA QR poster in the waiting room, a link on WhatsApp, a code sent home with a school class — every route carries your practice's details automatically.
They choose numbers or shapesTwo parallel versions of the test: classic numbers, or circles, squares and triangles that younger children find easier. The parent picks; the screening is the same.
ColourCheck rates the run honestlyA mid-test catch plate flags inattentive or bad-screen runs as inconclusive rather than pretending. Per-plate response timing happens invisibly in the background.
Suspicious results come to youBecause the link was yours, the referral is yours: "see your optometrist for a full assessment" points at your practice, never a generic directory.

Honest about what a phone screen can do.

ColourCheck states its limitations inside the app and never calls itself a diagnosis. It is a screening tool whose entire job is to find the people who need the real test — the one you do.

Built in

Small product, properly finished

Your brand

Branded to your practice

Practices pay monthly for a branded version — your name and details apply automatically to every link, QR code and referral screen you hand out.

Honesty

Inconclusive is an answer

A catch plate that everyone can read spots a distracted child or a badly set-up screen, and the run comes back "inconclusive — try again on another device" instead of a misleading result. No screening is perfect, so every result also says what it can't tell you.

Waiting room

Tablet mode

A waiting-room mode turns any tablet into a self-serve screening station between appointments, and clears itself for the next person.

Schools

School screening codes

Create a code for a school or a class. Its page names the school and your practice, and every result offers a printable letter for parents that names you as the sponsoring optometrist.

Education

A colour vision explainer

A whole educational section on colour vision deficiency — what it is, what it isn't, and what a full assessment involves — in plain language.

FAQ

Common questions

Is ColourCheck a diagnosis?

No — and it says so, inside the app, in plain language. Phone screens vary and screening is screening. ColourCheck's job is to sort "probably fine" from "worth a proper look," and to send the second group to your chair for a full colour vision assessment.

Why two versions of the test?

Numbers work well for older children and adults; circles, squares and triangles are easier for younger children who can't yet read digits confidently. The patient or parent chooses at the start, and both versions screen the same way.

What stops a bad screen or a distracted child skewing the result?

A catch plate in the middle of the test that everyone can read, whatever their colour vision, because its number or shape stands out by lightness rather than colour. Miss it and the run comes back inconclusive, with a suggestion to try again on another device. Like any screening, ColourCheck can still miss a mild colour vision difference, or suggest an assessment that turns out not to be needed, and every result says so.

Where do referrals go?

To you. The test reaches people through a link or QR your practice handed out, so your practice details apply automatically — there is deliberately no generic "find an optometrist near you" button anywhere in the product.

Can I try it before paying?

Yes. Every practice gets 14 days free, and nothing is charged until the trial ends. You can also take the screening yourself in the demo, or look around a sample practice's screen, without signing up.

What does ColourCheck store about the people who take it?

No names, contact details or ages. Each finished screening is kept as an anonymous result (the answers, the outcome and the date) so your practice can see its totals. If someone asks for their result by email, the address is used once to send it and isn't kept.
