About Uinston - UX helper

100+ UX principle checks

Audits the page against a large library of established UX and user-psychology principles, including Hick's Law and Fitts's Law.

Violation detection

Clearly flags where the interface breaks recognised UX norms, so you know what to fix first.

Improvement suggestions

Highlights areas that could be enhanced to lift engagement and page metrics.

Runs right in the browser

Installs as a lightweight Chrome extension and analyses whatever page you are currently viewing.

Behavioural-science lens

Frames findings in terms of user psychology patterns, not just visual polish.

Uinston is a browser-based UX review assistant distributed through the Chrome Web Store. Once installed, it inspects the page in front of you and produces a structured analysis of how the interface uses — or breaks — well-known UX and behavioural-science principles. Rather than generic design advice, it points to specific patterns such as Hick's Law (choice overload) and Fitts's Law (target size and distance), alongside a library of roughly one hundred further heuristics.

The tool is aimed at people who ship web pages and want a fast, second opinion before release: product designers, growth marketers, founders and front-end developers. Its output flags principle violations that tend to suppress engagement, and it also surfaces areas of potential enhancement, so improvements can be prioritised rather than guessed at.

Uinston is built and published by the team behind uinston.com. It is a lightweight extension (around 50 KB) and offers in-app purchases, which suggests a tiered model where additional analysis capacity or features can be unlocked inside the product. Because it lives in the browser, reviews happen on live sites, staging URLs or competitor pages alike — useful for benchmarking as well as self-auditing.
