This is something that I have been thinking about on and off and would like to see if there are frameworks that can give as close to native performance as possible. (Mobile, desktop etc)
The other issue is that out of the box, we can’t integrate any mobile purchases flows and the developers have to rely on the wrapper framework to do so (which we don’t provide).
@Guz, goNative certainly works, but you could even look at doing something like a Web View in Android(not developed apps for iOS, but there should be an equivalent) to achieve the same.
