iOS app outperforms core-js in 6 of 7 categories, with a stronger composite score (74 vs 72). core-js leads in no categories.

When to choose core-js

core-js doesn't clearly lead iOS app in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.

When to choose iOS app

Choose iOS app when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.

How this comparison was built

Scores are medians across 1570 audited core-js sites and 58 audited iOS app sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.
