Has anyone in here looked at this for differences between React Native? https://getexponent.com/

"Exponent is a mobile app development tool that enables you to build high quality native iOS and Android applications using JavaScript and deploy them effortlessly. Writing an Exponent app is like writing a React Native app, except you never need to open Xcode / Android Studio, or write any native code. The Exponent SDK provides access to system functionality such as contacts, camera and social login... Exponent also provides UI components to handle a variety of use-cases that almost all apps will cover but are not baked into React Native core, these include icons, an image lightbox, a loading overlay and more."
