Business/application logic can be 80-90% of an app’s code, and all of it can be reused across platforms. The actual UI rendering is just a small part of it.
In the UI code, some of it does have to differ across platforms but it’s mostly the lower level components like buttons, text fields, etc. Some product UI code built on top of those abstractions can be reused across platforms.
Sure, but it’s still more work than a web UI, and using a web UI is a lot more flexible. For example, say you want to render a chart or some other visualization. It’s trivial to do with a web UI, but can be a tricky problem with native widgets, especially if you want to keep the UX consistent across platforms. I agree that using React Native can work fine in a lot of cases, but I can also understand the appeal of using the web UI stack. Another aspect is likely familiarity, people use the tools they know, and if somebody is already comfortable with a particular ecosystem they’re likely to leverage it.
