App Store High Rejection

Guideline 4.3 — app is too similar to other apps (spam)

Apple judged the app too similar to your other apps or to existing apps, or built from a template without meaningful differentiation.

Typical wording

Guideline 4.3(a) - Design - Spam. We noticed your app shares a similar binary, metadata, and/or concept as apps submitted to the App Store by other developers, with only minor differences.

Common causes

White-label or reskinned apps
Purchased templates
Multiple bundle IDs for one product
Saturated category

What to check

Comparison matrix against the similar apps
Whether the portfolio could be one app with a picker
Template origin and customisation depth

Fix, reply or appeal guidance

Differentiate meaningfully or consolidate into a multi-tenant app
Do not resubmit with a new icon, bundle ID or account
Appeal only with a concrete comparison
