Web developers have been claiming forever that the web will take over and nobody will need apps or software outside of a browser, but is not close to becoming true yet on mobile. If you're considering making a poor web app or a poor native app, your time is probably better spent on the web app. Even if you're crafting an average app, it's probably a better use of your time to just get it working on the web. But the UX and speed that is possible in an exceptional native app is just not possible on the web today.

Airbnb absolutely benefits from having a fantastic app experience. Facebook and Twitter absolutely benefit from having exceptional apps. Google's iOS Gmail app isn't even a very good app (slow performance from being a web wrapper?) but it's still way better than using the web app in Safari. Basically if user experience and speed are a high priority and you are capable of making a decent app, the web is not a substitute for a native app.
