Here is why the startup I write code for wants an app first and browser code second. We actually would prefer the browser by leaps and bounds, cutting the need for central servers and decentralization is a core idea, you should remain in control of all your data. The problem: The only viable way to store a significant amount of data in the browser is IndexedDB. Which allows you only some storage of the total available - and, much much worse, the browser can wipe the data at any time without warning. It simply is not possible to provide our data-storage related system without either a central server backing up the browser "app" - or writing an app for iOS and Android.
