4.3(a) spam rejections: what Apple's text says and how to make an app distinct
By Niv Nisanov ·
Guideline 4.3 is the spam rule, and it is the guideline with the most public cases in our log. We have 12 public posts from developers rejected under it, dated Apr 14, 2026 to Oct 25, 2026, and 8 of them are from October 2026. That is a small set of public posts, not a measure of how often Apple uses 4.3. Here is what Apple's text says, what those developers reported, and what you can change.
What Apple's guideline says
(a) Don’t create multiple Bundle IDs of the same app (for example, submitting a separate map app for every city in the world instead of a single worldwide map that allows users to search any city).
(b) Don’t submit apps that are indistinguishable from what's already widely available.
Apple, App Review Guidelines, 4.3 Spam. Part (b) goes on to name categories Apple calls well established, such as dating, flashlight, sound effects, wallpaper, simple timers, and fortune telling, where new submissions need a meaningfully different or improved experience.
Apple's help article on copycat rejections puts the same idea positively: "Create apps that provide a new experience or a unique spin on an existing concept." (Apple, 4.1 Preventing copycat and impersonation rejections.)
What the 12 developers reported
Outcomes, as the developers posted them: 3 approved, 1 pending, 7 outcome unknown, 1 stopped trying. Several posts describe more than one app rejected at the same time, and some posts cite 4.3 without a sub-letter; we file those under 4.3(a). The 3 approved cases:
- 4.3(a) on a new app, approved a month later after a demo video. What they did: Appealed (no effect), then resubmitted with a demo video showing how the app differs from competitors. Approved July 4 after a June 3 rejection, as stated by the developer (about one month).
- 4.3 Design Spam, approved 12 hours after a one-color change. What they did: Changed one background color and resubmitted. Approved about 12 hours later, as stated. The post says 4.3 Design Spam without a sub-letter.
- 4.3(a) on an update, approved after a later retry. What they did: Contacted Apple (no luck), paused, then resubmitted with a change. The post does not say what changed. Approved, per the post. Time to approval not stated.
One case is one data point. The developers' own accounts are linked from each case page.
How to make an app distinct
- Find what it resembles. Start with your own apps, then the template, kit, or tutorial you built from.
- If two of your apps overlap, merge them or remove one. That is what 4.3(a) is about: one app with variations, not many near-copies. Apple suggests in-app purchase for variations such as locations or teams.
- Change the core experience, not only the colors. Remove leftover template screens, sample assets, and boilerplate text.
- Rewrite the description and screenshots around your audience and what they get, not the category.
- In Notes for Review, say who the app is for, what it does that others in its category don't, and the exact path to see it. One approved developer above sent a demo video.
If you think it is a mistake
You can reply to App Review in App Store Connect to ask what the app was found similar to. Apple's help says not to use that reply to appeal; appeals to the App Review Board go through the Contact Us form (Apple, Contact App Review). Our 4.3(a) guide has the full fix list, and the decoder tells 4.3(a) from 4.3(b) when the message says which.
