For integration, please email us with a detailed description of what you’re trying to do, and the calls from the documentation you need. Adding all the calls of an API is much longer, and most of the time not necessary (and we can add them later). Depending on how much work is needed, we sometimes ask for a one-time fee for this (that’s what we call ‘sponsor a feature’).
For visits, we count unique users, and use their email/pw to identify them, so an app on a phone will likely be one person.
Also, we do generate native apps for iOS, but it’s still in beta.
PS: thanks to have different threads for unrelated questions, that makes the forum more searchable for other users
