A PWA is basically a hybrid of a web page and a mobile application. PWAs run on top of a script called a service worker that allows them to run like a regular app without the burden of a ton of code to slow it down. Since they do not rely on as much underlying code, PWAs are much smaller than their native app counterparts. Downloads are incredibly fast. It can be downloaded almost the very moment you hit the button, and unlike a website, it doesn’t matter how fast or slow the connection is—the app will load instantly, even allowing for off-line use and submission of data. Once network connection is re-established, the data will automatically be sent. You can also use the built-in features of your phone when using the app, Camera, Location Services, etc.
Productivity PWAs make every step in development faster with simple drag and drop functionality, but also have additional options for further development if desired, such as integration with other software programs like databases, as well as the ability to add design features by adding CSS. You can build and deploy an app in minutes, not weeks or months! The app installs on your smartphone or tablet (iPhone or Android) and looks just like the rest of your apps.
You don’t have to go through the App Store or Google Play process—just Share the App URL (for the Public to use OR only for your staff to use). You don’t have to compile code, and updates are dynamic and can be completed with ease, in real-time.
Unlike most native apps, PWAs work across platforms (iOS, Android), so you only have to build an app once. That makes it significantly easier to keep track of as opposed to traditional development. You do not have to worry about the different bugs you would normally find in testing for the iOS and Android versions.
Examples of PWAs
On an iPhone: Click the button on the bottom of your phone, then scroll down and select
On an Android Device: Click the 3 dot menu in the upper right corner and select
