What is the correct difference between mobile web and mobile app?

The major difference between a mobile app and a mobile website is that the mobile website is accessed by the user via the Internet (therefore requires being online) and the downloadable application is a separate app installed on the phone and can be accessed both online as well as offline.

Can we use same API for web and mobile app?

You could have a website, a mobile app, and a mobile web app accessing the same data using the same API, without needing to have a backend for each app implementation.

Do I need web app and mobile app?

Mobile applications need to be installed from the app store, while web applications can be easily viewed from any browser and thus do not need to be installed. Mobile applications can be accessed even offline, and that's not the case with web applications since browsers do not work without a proper internet connection.

What application that has both web and mobile version?

Snapchat, Instagram, Google Maps, and Facebook Messenger are some examples of popular mobile apps. Web apps, on the other hand, are accessed via the internet browser and will adapt to whichever device you're viewing them on.
