I have the LG G2..
and yes, it does adjust to the browser..
huge benefit of having an app would be for the notifications.. dont have to go through email for it..
if it costs money then start up a donations for a cause in a go fund me type of thing.. hell, Id put down a little money for that..
and have an app for each platform made.. advertise it on the forums home page with links.. i like apps because the notifications are easy access
