Progressive Web Apps (PWA) are going coming online in 2018 with Google expected to make a big push mid-year and Microsoft with native support in Windows 10 Redstone 4 in the coming weeks.

If you have an Android phone and are using the Microsoft Edge browser, you can start to use many of the sites already.

Here are two ways to get a PWA website to act like a typical app on your Android phone.

For those who want a deeper dive into what PWAs are and why they will matter for all OS platforms starting this year, check my in-depth article and video explainer:

Progressive Web Apps (PWA): What they are, and what they mean for Microsoft

Which sites support PWA?

Currently, there is no master list of sites that support PWA. Luckily, there are some big ones, including:

Other major sites include Alibaba, Medium, Flipboard, Snapdeal, Trivagao, The Weather Channel, The Financial Times, Pokedex.org, GitHub Explorer, Flipkart, Offline Wikipedia, and Forbes. And there are thousands more.

How you know a site is PWA-enabled is tricky. Websites rarely announce such a feature, but one way you usually can tell is when you login to the site. That usually prompts a pop-up notification asking you to pin to your Home. The site may also ask to send you notifications – these are PWA features.

You can see this in action below when going to mobile.twitter.com and what happens after I login:

You often don't get a PWA notification until you login.

While that may seem like a nag (or even spammy) that is how a PWA-enabled site lets you know it can act as app. (Microsoft is getting around this by putting PWA-enabled apps into the Microsoft Store as "real" apps avoiding confusion or discoverability issues).

So, problem solved. You pinned the Twitter Lite app to your Home screen and you now have a PWA.

But what if you said 'no' to the prompt? Twitter won't ask you each time you go to mobile.twitter.com to pin to your Home screen, so how do you get it back?

Fixing problems: login in (again)

One trick that usually resets the PWA prompt on websites is just logoff and login again from that website.

If that doesn't work, try logging off and then clear the browser's cache (tap the ellipsis > Settings > Privacy > Clear browsing data) and then re-login. That should cause the PWA-prompt to reappear.

Use 'Add to Home screen'

One easier trick than the above is simply using Edge's 'Add to Home Screen' feature.

While a user can add any website as a pin to their Home screen – even if it's not PWA-enabled – when the site has a PWA this will create that necessary shortcut. Here is how to do it:

  1. Ellipsis menu (lower right corner)
  2. Choose Add to Home Screen
  3. Select Add and OK after the prompts

If you now go and launch Twitter through that shortcut suddenly it looks like a full-fledged application with no Edge browser "chrome" (boarders, controls).

Twitter as a PWA looks just like an app.

And that is how a PWA looks and works!
