Does that involve shipping a native wrapper for your web app?

If so, you have the extra cost, effort and bureaucracy of building and deploying to all the different app stores. Apple's App Store and Google Play each have various annoyances and limitations, and depending on your market there are plenty of other stores you might need to be in.

Sometimes you do need a native or native-feeling app, in which case a native wrapper for JS probably is a good idea, other times you want something lightweight that works everywhere with no deployment headaches.

As much as I agree with app deployment headaches, apps provide something a website cannot (except PWA) - ability to do stuff offline, log and register data which can be uploaded when connection is re-established. When talking about user experience - launching the app, selecting new -> quote -> entering details -> save -> locking the phone without worrying or waiting, knowing that it will eventually get uploaded, is much more convenient than walking with the phone around the property to get better reception to even load the new quote page.

UX matters, and user does not care if the native wrapper or 500kB of js is there or not, as long as the job is done conveniently and fast.
