Web app vs mobile app

Also called: web app, mobile app, native app, app, iOS app, Android app, app store

A web app runs in a browser at a web address, on any device. A mobile app, also called a native app, is installed on a phone from an app store. Many products start as a web app because one version works everywhere.

For example: Customers open your booking tool by visiting a link on their phone. That is a web app. If they must download it from an app store first, it is a mobile app.
