iOS Keeping track of new user registration?

[jsnuff1]

I have an app that uses another companies services, and would like to know how many new registrations my app does from my end.

What would be the simplest and accurate way to keep track of this?

Should I have my app call a certain private website I have set up each time a successful registration is performed, and have some sort of counter set up on that website?

Well, unless the services your signing them up with work with your then you will really never know the true number. You could have a link between but that will just give you how many people attempted to register, it would tell you if they actually did or not.

well i handle the new user registration within my app, so my app knows if a success registration has occurred.
