It is not uncommon for a startup to develop a web app, an iPhone app, and an Android app. When management is convinced that a web app can be just as engaging as native they will decide to focus solely on the web app and get to market much quicker. Making a web app installable results in increased discoverability, traffic, visitor retention, sales per customer, and conversions. I believe that this project proves beyond doubt the immersive potential of browser APIs.
Progressive Web Apps bring speed and reliability to the web by supplying features that historically have only been available to native apps including offline access, responsiveness even when the network is unreliable, home screen icons, full screen experience, push notifications and background sync.
The Progressive Web App represents the single greatest leap in engagement opportunity since the introduction of the browser. Because of its intimate relationship with the phone the potential to influence the micro-moment behavior of its user is vast and largely unexplored.
Your website becomes a native app in both experience and performance. Your PWA is a first class citizen on an iPhone or Android. It resides on the homescreen and in the app drawer.
When it is tapped it will respond instantly with a custom splash screen even while offline.
Expanding what the web can do with features like file system access, media controls, app badging, WebAssembly, and full clipboard support. All of these capabilities are built with the web's secure, user-centric permission model, ensuring that going to a website is never a scary proposition for users.
