Web App

Web applications cannot always be perfectly adapted to the hardware of the device in use, but work on all operating systems and on all devices, which have one of the browsers supported by the web app. So a single app is enough to be able to be present on all platforms, even if it is not always possible to optimize it for all browsers.
A further plus point lies in the resolution of security flaws: in the case of native apps, they can only be resolved by downloading a new version or update, while in a web application the necessary security updates are made directly to the software, so that all users automatically access the most secure version. Furthermore, the overall costs for web apps are lower and are created faster.

A normal web app, in simpler terms, is a website designed to be accessible on all mobile devices so that the content fits the device screen. It is designed using the web technology stack (HTML, CSS, JavaScript, Ruby, etc.) and works via a browser. They offer various features and functionality of the native device. However, it completely depends on the browser used by the user. In other words, it may be possible to access a feature of the native device on Chrome but not on Safari or Mozilla Firefox because browsers are not compatible with this feature.
