The notice arrives in Resolution Center reading roughly like this: your app duplicates the content and functionality of other apps submitted to the App Store. No app is named. Nothing tells you which of your decisions caused it.
The first useful thing is to check whether you got 4.3(a) or 4.3(b), because they are different accusations and the guideline text splits them.
4.3(a) is about a specific overlap. Often the app being duplicated is your own. If you shipped several builds off one codebase, one per niche, that is the case being made, and it is normally right.
4.3(b) is category saturation: your app resembles a lot of other apps in a crowded space. Nobody is accusing you of copying anyone in particular.
4.3(b) got noticeably harder on 9 June 2026. The revision lets Apple reject an app for being indistinguishable from what is already there, and it names categories where a new submission has to offer a meaningfully different experience to get in at all: dating, wallpaper, fortune telling, flashlights, sound effects, simple timers. The same revision lets Apple remove apps that are already live in those categories if they are not improved or do not find customers. If you were rejected under 4.3(b) after that date, this is the text you are up against.
Developers lose days trying to identify the app they supposedly cloned. Apple does not tell you and support will not either. Answer without it; a wrong guess in writing is worse than no guess.
These are two different doors and people confuse them constantly.
Resolution Center is a reply to the reviewer who rejected you. Use it when you think they misread the app. Turnaround is typically a day or two and most 4.3 cases finish here.
The App Review Board hears the argument that the guideline was applied incorrectly. It is slower, it is not a second opinion on taste, and if you escalate before saying anything in Resolution Center you have spent your escalation on a case nobody has heard yet.
Neither door does much where you genuinely shipped six variants. Apple wants one app. Fold the niches into settings, pull the rest, resubmit.
"Our app is unique and took months to build" is in nearly every 4.3 reply ever sent, so it lands as noise.
Instead: what the app does that the category default does not, with the screen named and the taps to reach it. Where the content came from and what gives you the right to it. If you have other apps live, raise them before the reviewer does and explain why they are not one app. If there is a template underneath, say what you built on top; denying it when the binary shows otherwise ends the conversation.
One screen of text. The reviewer is working a queue.
Paste your rejection and what the app does. You get an appeal letter written for that exact notice, back within an hour, for $29 CAD. A full sample letter is on the front page so you can judge the writing before paying.
It is not legal advice and it is not a promise Apple says yes. When the rejection is one no letter fixes, the letter tells you that and what to change instead.
