A web app is a software application that runs inside a web browser, such as Google Chrome, Microsoft Edge, Mozilla Firefox, etc. Users can use the web app via an Internet connection, without having to download or install any software on their device.
Web apps differ from native apps, which are apps designed for a specific platform, such as iOS or Android, and which require installation on the device. Some advantages of developing a web app over native apps: they are compatible with different devices and operating systems; they are easy to update; development and distribution costs are reduced.
