How To Install a Web App (PWA) on Windows, Mac or iPhone and Android

What is a Progressive Web App (PWA)?

Progressive Web Apps [*] are Web Apps that behave more like native apps. You can “install” them to give them a dedicated window and shortcut on your PC. They can also load quickly, and show you notifications—just like normal apps. 
They are the future of software because they work everywhere, they are safe and they install and update almost instantly.

Examples and success stories using PWA Web Apps

• Twitter Lite [*]
  It became the default mobile web experience for all users globally in April 2017. Twitter developed Twitter Lite to deliver a more robust experience, with explicit goals for instant loading, user engagement and lower data consumption.
• Starbucks [*]
  Starbucks revealed that they are already seeing significant success by replacing their mobile app with a PWA. Starbucks reportedly say they doubled the number of people who used the website to place orders each day, with desktop users now ordering at about the same rate as mobile users.

Requirements
On desktops and laptops, as of early 2020, you need Google Chrome.

How to install?

• Start Google Chrome and navigate to the login screen.
• It is best to wait to be logged in (making sure the web app is fully active).
• You will see a little (+) appear in the address bar, on the right, in Chrome.
• Click on the (+) to install.
• As an alternative, if you do not see the (+ install), click on the (...) button, with 3 vertical dots, right on Chrome’s address bar.
  This pops up a menu, look for “Install ...”, and click on this install menu.
  

That is it. Nothing special about it. As mentioned, because there is no download or software to actually install, installation itself is almost instant. This is normal.
