Hi everyone,
I’m currently working on a project based on the Telegram iOS open-source code. My goal is to build an unofficial Telegram client with Telegram’s permission (they have publicly allowed third-party clients under their open-source license).
My app includes unique new features and UI improvements that are not present in the official Telegram app. Essentially, it’s Telegram plus additional features — built from the official source, but extended significantly.
However, when I try to submit my app to the App Store, Apple rejects the build under Guideline 4.3(a) - Design - Spam with this message:
“We still 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. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps.”
I completely understand Apple’s intent to prevent low-effort clones or spam apps. However, in my case, this is a legitimate open-source-based project with new and unique functionality. I’ve spent a lot of time designing new features and improving user experience — this is not just a rebrand.
Has anyone else experienced this issue when submitting an app based on an open-source client (like Telegram)? Is there any recommended approach to help Apple differentiate my app as a distinct and valuable product?
Any advice or guidance would be greatly appreciated! 🙏
— Additional Context:
The app is based on Telegram’s open-source iOS client.
The app includes new features and UI changes.
It’s submitted under a different name, icon, and bundle ID.
I’m happy to comply with any additional clarification Apple might need.
Thanks in advance to anyone who can share insight or experiences with this kind of rejection.
