Scout Review

Written by AI from measured evidence, scored out of 100.

Sensitivity Converter is a focused, fast, well-built free tool for a real and specific problem: keeping your aim consistent when you switch FPS titles. The math is transparent — it shows the yaw formula, the exact cm/360, the retained-precision check and the rounding error — which is exactly the credibility a competitive player needs. Design is above average with a clear result hierarchy, though the low-contrast guide text and mismatched accent colours keep it from feeling finished. Usability nails the core task and then buries it under documentation. Security and accessibility are solid table stakes with no published audits or a11y statement. Growth is limited by a niche, free, no-network-effect category, but the wedge over a desktop matcher is real.

Measure by measure

Usability

Core convert-and-copy flow is fast and clearly labelled, with advanced FOV/yaw tools tucked into collapsibles. The wall of documentation and comparison table below the calculator buries the next step.

Design

Clean, precision-tooling aesthetic with a strong result hierarchy and disciplined monospace numerics. Undermined by low-contrast grey body copy and four competing accent colours on the mode row.

Speed

Lighthouse 98 mobile / 100 desktop, LCP 944ms, CLS 0, TBT 19ms. A genuinely fast static-feeling page with no layout shift and no lag complaints in the evidence.

Security

HTTPS with HSTS plus frame, content-type, referrer and permissions headers — solid baseline. Missing CSP, SPF and DMARC, and no published audit or security page. Fine for a free browser tool, unremarkable otherwise.

Accessibility

Lighthouse accessibility 100/100 with labelled inputs, a skip link and responsive layout. No published a11y statement or multi-language support, which caps it below the top of the band.

Growth

Real, specific pain for competitive FPS players, with documented yaw profiles and FOV matching as a genuine wedge over a free desktop matcher. Niche ceiling, no network effects.

Improvement areas

Low-contrast grey body copy in the field guide hurts readability on long reads.
Inconsistent accent colours and button weights across the mode and utility rows.
Missing CSP, SPF and DMARC; no published security or accessibility statement.
Documentation and comparison panels crowd the page below the calculator.

Design & Usability

The homepage is built like precision instrumentation and mostly earns it: the oversized blue monospace result is the unmistakable focal point, numerics stay monospace across the stat strip and equation panels, and the field guide uses a sticky sidebar index that suits a technical audience. The cracks are cosmetic but real — light grey body copy on cream makes the long guide tiring to read, and four different accent colours on the mode buttons make the action row feel like four products stitched together. Usability is strong where it counts: labelled inputs, a swap control between FROM and TO, and an immediate Copy button keep the core task to seconds. Below the fold, though, the guide, saved setups and comparison table all compete, so a user who wanted one number has to scroll past a lot of documentation to find the next step.

Speed & Security

Speed is the standout: Lighthouse reports 98/100 on mobile (LCP 944ms, CLS 0, TBT 19ms) and a perfect 100 on desktop, with no lag complaints in the collected evidence. For a page this dense with equations and tables, that is genuinely well-built. Security is competent but stops short of thorough: HTTPS is enforced with HSTS, and frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy are all present, but there is no Content-Security-Policy and no SPF or DMARC records — 8 of 12 checklist points. There is no published SOC 2, ISO or bug-bounty program, which is normal for a free browser tool but keeps the score in the middle of the band. Settings live in the browser and share links carry your setup, which is disclosed on the page.

Accessibility & Growth

Accessibility is a genuine strength: Lighthouse's axe-based audit returns 100/100, inputs are labelled, a skip-to-content link exists and the layout is responsive. What holds it below the top of the band is the absence of a published accessibility statement and any multi-language support — the tool is English-only. On growth, the idea is sharper than most: competitive FPS players genuinely lose muscle memory switching between CS2, VALORANT and Apex, and this site answers that with documented yaw profiles, cm/360 matching, FOV and monitor-distance matching, an ADS measurement helper and saved setups. Against the only listed alternative — KovaaK's free desktop matcher — the browser-based, no-install, no-account angle is a real wedge. The honest limit is the category: a free niche utility with no network effects and no data advantage, so it can win its corner but not compound.

Conclusion

If you bounce between CS2 and VALORANT and your aim feels off every time, this does the job in seconds and shows its work while doing it. The transparency around yaw coefficients and retained precision is the differentiator — it tells you to verify in-game rather than pretending the number is gospel. Where it needs work: tighten the contrast on the field guide, unify the button styling, and move the saved-setups and comparison panels behind a tab so the calculator stays the hero. Add a CSP and DMARC records, publish a short accessibility statement, and this moves from 'good free tool' to 'the one you bookmark.'

Suggestions for improvement

Raise body-copy contrast in the field guide — light grey on cream fails long-read comfort.
Unify the mode-button and utility-row styling into one consistent action group.
Add a Content-Security-Policy header and SPF/DMARC records to complete the security baseline.
Collapse the guide, saved setups and comparison table behind tabs so the calculator stays the focus.
