Measured on six things

Free birth chart, Saturn Return & synastry calculators plus AI Astrologer chat and personalized reports.

Design

Detailed birth-chart wheel and consistent green CTAs are on-brand, but the homepage hero renders as a near-empty white viewport, undercutting first impressions.

Scout Review

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

Astrology Geeks is a calculation-first astrology tool that gets the fundamentals right: free Swiss Ephemeris calculators with no signup, sample reports before purchase, and a clear Free vs Plus split. The birth-chart wheel is genuinely well-designed. The problems are fixable and specific — an empty homepage hero, a 4.2s mobile LCP, missing security headers, and accessibility audits that fail on contrast and touch targets. Against Co-Star and Astro.com it has a defensible middle position: more accurate and less jargon-heavy than the former, more conversational and modern than the latter. Whether that middle is big enough to justify $19.99/mo is the open question.

Measure by measure

Usability

Free calculators with no signup, sample reports for every paid product, and a clear Free vs Plus table make the path to value short and legible.

Design

Detailed birth-chart wheel and consistent green CTAs are on-brand, but the homepage hero renders as a near-empty white viewport, undercutting first impressions.

Speed

Desktop Lighthouse hits 99/100 and mobile 85/100 with zero layout shift, but a 4.2s mobile LCP drags the experience on phones where most users arrive.

Security

HTTPS, HSTS, secure cookies, SPF and DMARC are all in place, but no CSP, no frame protection, and no published audit or security page leave gaps.

Accessibility

Lighthouse a11y scores 90/100, but failing contrast, touch-target, ARIA and accessible-name audits plus no WCAG statement show real gaps remain.

Growth

A real, specific wedge — Swiss Ephemeris accuracy, no-signup free tools, AI grounded in placements — aimed at a crowded but hungry astrology market.

Improvement areas

Homepage hero renders nearly empty above the fold — biggest conversion leak.
Mobile LCP of 4.2s exceeds Google's 2.5s threshold; compress the chart-wheel asset.
Missing CSP, X-Frame-Options, Referrer-Policy and Permissions-Policy headers.
Failing accessibility audits on contrast, touch targets, ARIA and accessible names; no WCAG statement.

Design & Usability

The design story is split: the birth-chart wheel and green CTA system are polished and on-brand, but the homepage hero renders as an almost-empty white viewport, which is the single worst place to lose a visitor. Usability is stronger — free calculators with no account, sample reports linked for every paid product, and a clean Free vs Plus comparison table make the path from landing to value short. The 3-charts-per-day and 3-AI-messages-per-month free limits are honest and clearly stated. Fix the hero and this jumps several points on design alone.

Speed & Security

Speed is a tale of two devices: desktop Lighthouse lands at 99/100, but mobile sits at 85/100 with a 4.2s LCP — above Google's 2.5s 'good' threshold, likely from the heavy chart-wheel graphic. CLS of 0 and TBT of 61ms show the engineering is otherwise tight. Security is competent but incomplete: HTTPS enforced, HSTS, secure cookies, SPF and DMARC all present, yet no CSP, no X-Frame-Options, no Referrer-Policy and no Permissions-Policy. Payments route through Stripe's billing portal, which is the right call. Add the missing headers and publish a short security page.

Accessibility & Growth

Accessibility scores 90/100 on Lighthouse, but the failing audits are substantive: insufficient color contrast, touch targets too small, prohibited ARIA attributes, and visible text labels that don't match accessible names. There's no WCAG conformance statement or accessibility page. Growth is the more interesting question. Astrology Geeks has a genuine wedge — Swiss Ephemeris-backed calculators, no-signup free tools, and an AI astrologer explicitly grounded in the user's placements rather than generic sun-sign fluff. Against Co-Star (social, app-first, shallow reports) and Astro.com (deep but dated and jargon-heavy), the positioning is coherent. The limits: the category is crowded, the $19.99/mo Plus tier competes with free alternatives, and the AI-grounded-in-placements claim is only as good as the model behind it. Early traction (36k+ charts, 1.3k+ users, sub-year-old domain) is context, not proof.

Conclusion

If you're astrology-curious and want a real chart without an account, this is a solid free starting point — the calculators are accurate and the takeaways are readable. Pay for Plus only if you'll actually use the 250 AI messages and the monthly forecast; otherwise the one-time reports are the better spend. For the maker: fix the hero, compress the chart-wheel asset, add CSP and frame protection, and publish an accessibility statement. None of those are hard, and all of them are currently costing you conversions.

Suggestions for improvement

Fix the homepage hero — the top viewport renders nearly empty, which is the single biggest conversion leak.
Compress or lazy-load the birth-chart wheel graphic to bring mobile LCP under 2.5s.
Add CSP, X-Frame-Options, Referrer-Policy and Permissions-Policy headers to close the 5/13 security gaps.
Publish an accessibility statement and fix the failing contrast and touch-target audits flagged by Lighthouse.
