An eye-tracking literacy app that runs on an ordinary phone camera is expanding into its third country, promising to flag struggling readers early. Here is what it measures, what the reading science says about it, and what to ask when any screening tool flags your child.

Common questions

Does eye tracking detect dyslexia?

No. Eye-tracking software measures where a child’s gaze lands and how long it stays there. Keith Rayner’s decades of research show that struggling readers fixate longer and backtrack more, so gaze reflects how hard decoding feels. It does not reveal why. The American Academy of Pediatrics, the American Academy of Ophthalmology, AAPOS, and the American Association of Certified Orthoptists state jointly that vision problems do not cause dyslexia. A halting gaze is the visible cost of effortful decoding, not its source.

What should I do if a screening tool flags my child’s reading?

Ask three things: what the tool measured, what instruction changes next, and where your child’s data goes. Then keep the flag in its place. A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing, or medical cause, pursue a professional evaluation too. That is the only route to those supports.

Are eye-tracking reading apps scientifically validated?

The research behind the signal is solid: skilled and struggling readers show measurably different gaze patterns. Whether a phone-camera product accurately identifies which children need help is a separate question, and it is answered by validation studies. READ for School’s public page cites none, and its claim that the assessment “diagnoses true reading ability” stands unverified. Ask any vendor, and any school adopting one, for the published evidence.

What actually helps a child who struggles with reading?

Direct teaching. The National Reading Panel found that systematic phonics instruction significantly improves reading achievement, and reading also draws on more than one system: language, attention, memory, processing speed. A phonics-only question set will not surface a co-occurring challenge in another system, so watch the whole picture: how your child hears and holds sounds, follows instructions, and keeps their place on a line of print. And per the American Academy of Family Physicians’ Choosing Wisely list, vision therapy is not a dyslexia treatment.
