Udemy and Upwork has built on which technology? (technology used for website and for native app (Android & iOS))

Question

I have a requirement to build an app which will be the combination of Udemy and Upwork . The app should work as a website and as a native app.

1. I m concern about which technology should i use for FrontEnd?
2. Instead of using 3 technologies (for 1.Website 2.Android 3.iOS). I want to precise my development.

as I am the user of Udemy, I have experienced some differences in design in website and in android app, so my questions is Has the Udemy app built in different technologies for website and for native app?

I need some suggestions which technology should i use to build app?

Answer 1

React and React Native could be good options if you like to keep the development process similar through web- and app development. My second recommendation would be to use Apache Cordova/Adobe Phonegap.

Maybe BuiltWith could be a useful tool to check what technology is used to build a specific website.
