I feel the same. Take the Telegram app as an example: it's so slick, responsive. Even a simple button click doesn't work well on the web due to the long response time between clicking and seeing a response.

Additionally, apps allow for good offline functionality (for times when you're not near a cell tower), which I feel is important even with ubiquitous internet access in the 1st world.

The solution I feel is to have better sandboxing functionality in mobile Operating Systems.
