Although app and mobile web usage is pretty much neck and neck, app usage seems to be creeping its way ahead.
As of right now, both app and mobile web coexist. There are still a good amount of people who use mobile web, but more and more companies are building custom applications for their brands, and it makes sense to do so. For instance, a custom app can be made compatible for a specific device, or multiple devices while web usage is more compatible on a desktop.
Expedia, a popular travel booking website, has invested in their app products and are using responsive web design which helps them make sure their app can be accessed on any device. This makes the experience a good one for clients.
