Written by AI from measured evidence, scored out of 100.
Simple Calculator is a fast, free, and mobile-friendly collection of 40+ calculators with a UK focus. Design is average but functional, usability is decent with clear categories, and speed is excellent. Security and accessibility have room for improvement. Growth potential exists in the UK niche, but competition is fierce. A solid start for a new site.
Clear category navigation and no registration. But no search bar, repetitive card descriptions, and dense grids hurt scannability.
Consistent card grid and icons, dark navy theme. Repetitive subheads and cramped hero pills reduce polish. Average but functional.
Lighthouse mobile 98/100, desktop 100/100. LCP 2.2s, CLS 0, TBT 60ms. Exceptionally fast and lightweight.
HTTPS and HSTS present, SPF/DMARC set. Missing CSP, frame protection, and other headers. No compliance certifications found.
Lighthouse 86/100 with contrast, lang, landmark, and label issues. No a11y statement. Keyboard navigation likely works but not verified.
Real problem, UK-specific niche, but crowded market. Differentiators exist but not enough to stand out yet.
The site uses a consistent card grid with icons, making it easy to scan. Dark navy theme with blue accents is decent. However, repetitive subheads and cramped hero pills reduce polish. Usability is solid with clear category navigation, but the lack of a search bar and generic card descriptions hurt scannability. Overall, it's functional but not memorable.
Performance is outstanding—Lighthouse scores 98/100 mobile and 100/100 desktop, with fast LCP and zero layout shift. Security is basic: HTTPS and HSTS are in place, but missing CSP and other headers. No compliance certifications found, which is typical for a small site. Speed is a clear strength; security is adequate but not exceptional.
Accessibility scores 86/100 but has notable issues: contrast, missing lang, no main landmark, and label problems. No a11y statement. Growth potential is moderate—UK-specific tools like stamp duty and EV calculators are a differentiator, but the market is crowded with established players. The idea is sound, but execution needs to stand out more.
Conclusion
If you need quick UK-specific calculations without signing up, this site delivers. It's not going to win design awards, but it's fast and covers a wide range of needs. With some polish on accessibility and a search bar, it could become a go-to resource. Worth a bookmark for UK homeowners and students.
