Hi, I'm working on an app that acts as a platform to link tourists up with subject matter experts for a specific topic in a specific city. When someone purchases the service, they get a few things. First, they get access to an in-person meeting with the subject matter expert and will schedule the meeting in the app. Second, they get a city guide so they have something like a list of places to go see (view the list in the app). Third, they can message the subject matter expert to ask any follow up questions. Will this app require the use of Apple's In-App Purchasing or an outside service like Stripe?
I greatly appreciate any insight/guidance on this question. I'm worried about spending too much time on it and then getting rejected when submitting it to the app store.
