As someone who is about to embark on a similar route, that's interesting and exciting to hear. Was it both Android and iOS? If so, how much of the codebase/time was spent on shared code versus needing to write platform-specific portions?

I've seen the Facebook post about developing Ads Manager (though it glosses over some details), but it would be interesting to hear other people's experiences.

We built it for iOS, but I expect Android would have been a similar experience (albeit with much more cross-device testing required).

Hard to say how much of it was platform-specific, since we only targeted 1 platform (for now). But the large majority of the code we wrote exists in React components or in related JS files, so porting it over to Android should be a matter of decoupling the parts of the code that rely on native features (i.e. camera, navigation, etc).

A lot of that work is already happening in the React Native community so I expect the cross-platform support will keep getting easier.
