Interesting that you mention #2. This is what Instant apps want to solve. tbh I wonder if it is that much of an issue but we are probably going to test it at some point. About #1. I am not that convinced that they are easier to build. Well they are, but building them in a way that fits each platform and performs well looks harder than making 2 apps. I should mention that I work in a 30 devs teams (half iOS, half Android) working on the same in-house app. I do believe that there is some potential to reduce duplicated work with something like j2objc. It is probably not the definitive expression of this concept, but it seems to me that it should be possible to share a lot of the business logic and this is what this tool aims to do. Some of the data objects should be shareable as well. All the rest : UI, integrating with the Home screen, notifications, services, et cetera is just very specific to the platform and IMO should be written specifically for each platform. I am still waiting for the perfect kotlin-to-swift library allowing that.
