It would be good, but not better. Why do people like apps so much? I hate them… Like, there is so much browsers can do these days, there is no point in having to install so much crap on our phones…
Why would I have to download an app that has so many permissions, syphon my data, run in the background and drain my battery, when 90% of the stuff can stay in the browser?
The only few advantages I can think off that an app can bring are the following:
they can work offline, some of them at least, half my apps probably won’t
better security, that’s mostly for bank apps, not really needed for many other cases
marginally faster load times
higher complexity, devs have a bit more freedom I guess
