The problem is JavaScript and standards that are only partially and/or incorrectly implemented. That's the only reason we see so many mobile apps instead of mobile sites: they are easier to code, deliver and monetize. Who wants to spend time and money to develop JS apps for all different browser/OS combinations? It's infinitely easier and cheaper to code native apps today. Solution: give us Dart or similar "real" language, and stop supporting obsolete browsers. Until then, we are condemned to live in the App world.
