I know this forum is more for suggestions, but I've seen so many mobile app posts so i decided to make this post. Tonight I'll be helping you make a PWA, public web app. On your wix dashboard, look in SEO for Meta tags, then add te following,
<meta name="apple-mobile-web-app-status-bar-style" content="default">
<meta name="apple-mobile-web-app-title" content="My Stunning Website" />
<meta name="apple-mobile-web-app-capable" content="yes">
Default makes your header white, black transparent makes it white and pretty much removes the header. (These wont work on macOS or Windows)
Chrome (73 and up) is required for the next part, and you dont need meta tags for this part, but you will still want them for mobile.
In chrome on macOS, click the "... menu, then find "more tools", then click "New Shortcut", then select "Open in new window" which creates the app part of the launcher.
On ChromeOS, you can also do this, but it will be harder and certain versions of software dont support it anymore. You want to do this on macOS, because you can upload the .app file chrome generates of your website making a app that runs off of chrome, on windows it should run in the background, but on macOS chrome has to be running but you can minimize it to the dock. If you take some time, you can convert your .app file to a .exe file. I uploaded mine to Google Drive and unzipped the file that Drive zipped, I renamed it "MySite.exe" for the Windows app, you can do "MySite.app" for macOS. Sadly, I haven't been able to try this out on Linux, and I'm not sure if it would fully work.
Tell me how it works! Please comment on anything that doesent work as I'll try to help 🙂
