Cloning an existing app already on the app store

Whet do you mean exactly by cloning ?

But if it is the same app under another name, it should normally be rejected as spam. Unless you first remove the other app.

And even if it worked the first time, it could be rejected later during an update.

Im trying to build a app, kind of like discord, it will have a different branding but the concept behind the application will be similar to discord. it wont be the same exact app but similar features will be offered for the users. will this get rejected?
