App Store Guideline 4.2.3 explained: Minimum Functionality requirement

Guideline 4.2.3 sits in Apple's Design section and is most relevant to intellectual property and third-party rights.

This page summarizes the review risk in practical terms and links to the official Apple source for the exact rule text.

Apple will check whether the app, metadata, screenshots, and developer identity imply rights or affiliations you do not have.

Apple will check whether the app, metadata, screenshots, and developer identity imply rights or affiliations you do not have.

Third-party content, brands, services, downloads, and media access often require explicit permission.

Copycat risk can come from names, icons, screenshots, UI, or promotional language.

The app uses protected names, logos, interface patterns, media, or brand references without evidence.

Metadata implies endorsement, partnership, compatibility, or content rights that are not documented.

Screenshots or app content resemble another app, game, service, or Apple product.

Remove third-party references you cannot document.

Attach rights evidence in App Review Information when you do have permission.

Rewrite metadata to describe your own app without implying affiliation.

If Apple cited Guideline 4.2.3, reply with the exact change you made and where the reviewer can verify it.

If you believe the app already complies, provide concise evidence, navigation steps, and any supporting documentation instead of a generic appeal.

Keep the tone factual and cooperative. Avoid promising approval or arguing beyond what the submitted build and metadata can prove.
