IOS iPhone Facer account login

Why Facer application on IOS doesn’t allow to login to your account to purchase and save favourite as in Android?
Is there any future plans to add this feature?

I’ve posed the same question a few times and would really appreciate a response from @Facer_Official even if the answer is a “no.”

It seems to me that it’s a development issue rather than an Apple restriction since the app would not be impacting phone-to-watch interoperability.

I’m sure that the designers would also appreciate a new revenue source so that we could pay for faces from IOS applications.
