PWA - Progressive Web App
PWAs are not only responsive websites or the so called webapps, they can rather be installed which means that you can download the website and install it as real app. Because of that you can use the progressive app/website offline too. A well developed PWA behaves like a native app from the Appstore/Play Store.
For developers PWAs are a big advantage because they are easier to develop since the developer only needs one website/webapp and not many apps for different devices no matter if you have an iOS/Android/Windows or macOS device.
Therefore are PWAs the future of apps and websites.
