Show HN: I built a free ADHD test app on which millenials outperform genz on

A developer launched a free browser-based app that asks users to stare at a blank screen, framed as an ADHD symptom aid.

Developer dixitbavu posted a free web app to Hacker News on August 22, 2026, under the Show HN banner, describing it as a tool that "helps improve ADHD symptoms by making you look at a blank screen," per the HN submission.

The app, hosted at rawdog-one.vercel.app, is available on both desktop and mobile at no cost. No subscription, paywall, or sign-up is mentioned in the source. The headline on the submission also claims that millennials outperform Gen Z on the test, though no methodology, sample size, or data source is provided to support that assertion.

Beyond the brief description in the HN post, the app's underlying mechanism is a blank screen — the interaction, if any, is not detailed in the source. It is not described as a diagnostic tool, and no clinical backing or medical affiliations are cited.

The submission received 1 point and no comments at the time of posting, according to Hacker News. No additional sources corroborate the generational performance claims or provide further technical or clinical context.
