Let’s just start by saying both native and web development have their pros and cons. What you want to use might depend on your circumstance or prior skills with the technology.
Mobile Web Development
Lets first start with mobile web development. Most websites on the internet can be loaded with your phone using your browser. Certain sites are called PWA’s which stands for Progressive Web Applications. PWA’s prompt the user to install the website as an “application” so that it can be opened on their home screen with an app icon. However this is very limited and does not give access to the native plugins such as the camera and other components of the mobile device.
Native Development
Native development refers to developing applications using the official language of the device you are creating the application on. For example iOS uses Swift language and Xcode as their official IDE and Android uses Kotlin language and Android Studio as their IDE.
Developing applications that run natively on the operating system has it’s pros and cons. Creating an application for it’s native environment allows you to get full access to all the device hardware and the components of the operating system. It also allows you to create apps that run more efficiently then on a hybrid of web application.
A downfall of native development is that is that each operating system will have different code, this usually means separate development teams costing companies more money.
