What are the features of downloading web mobile applications?

When downloading web mobile applications (PWA - Progressive Web Apps), there are the following features compared to native applications from stores:

• No need to install from App/Play Store. PWAs are installed directly through the browser, simplifying the process for the user and bypassing store moderation.
• Use of Service Worker technology. This allows PWAs to work offline, receive push notifications, and cache resources for fast loading and better performance.
• "Installation" as adding to the home screen. The user adds the PWA to the device's home screen, where the application looks and functions like a native app. In fact, only necessary resources are downloaded, and a shortcut is created.
• Smaller size. PWAs generally have a significantly smaller size compared to native applications, as most content is generated on the fly and not included in the installation package.
• Dependence on the browser. PWAs utilize browser capabilities for their operation, which can affect performance and available features depending on the browser and its version.
• Limited access to system APIs. Compared to native applications, PWAs have more limited access to some device system APIs (e.g., Bluetooth, NFC in full), although support is gradually improving.
• No centralized update. PWAs are updated automatically when using the application, without the need to visit the app store. Service Worker manages the loading of new resource versions.
• Availability without physically installing an .apk/.ipa file. The user does not download or install a traditional executable application file.
• Fast loading. Thanks to Service Worker caching, PWAs can load much faster on subsequent uses.

These features make the process of downloading (or more precisely, adding to the home screen and caching) PWAs different from the traditional installation of native applications.
