One reason I prefer doing React is that retrofitting existing React stuff for React Native is better/easier than embarking on React Native from scratch.
The majority of these apps are about placing the existing product into the App Store for discoverability, and encouraging users to be “locked” into the app at the expense of a worse customer experience.
A web app, in a browser, automatically has support for opening multiple pages as multiple tabs, bookmarks, sharing pages. You can’t do that with 99.9% of apps.
I will also argue strongly that, again, react native is unnecessary even if you do want to package a native app. WebView based apps perform as well as a react native app, and most of the time with significantly less additional code. It also forces you to up your “mobile website” UX. In general the minuet you build a mobile “app” the mobile web experience gets neglected.
