White Label without using Appstores

I have subscribed for the white label feature and have an APK link for the android category which I can just share with my user without publishing to the Play Store --based on a tutorial video I saw with Santiago Uribe on youtube.

However, I did not find one for the IOS side. Is there a way to white label my app without submitting all the requirements needed to be on the Appstore? I want my user to be able to download the app just like the android version through a simple link.
