Webview based UI would be a nice way to update UI elements directly from the server. It would help users to not re-download/update entire application for UI related changes. You can use "service workers" for caching web pages to make them working on Offline mode. Also webview will help developers to update UI changes rapidly.
It's just a suggestion..

These discussions are good when the app hasn't already been made. At this point, they're pointless
BTW, After exploring more inside the Source code, I have found that Yes this app is already using WebView inside it...
so is this just wrapper over webview app ?
