A Splash (launch) screen appears instantly when your app starts up. It gives your PWA even more native-app-like feel.
Android Chrome automatically displays a splash screen for PWAs based on the icons, background color & names you provided in the manifest file.
It will also show the app name below the icon using the name property. The text color can't be customized because it's automatically taken based on contrast.PWA Manifest
This feature is available in latest iOS versions (11.4+).
Safari isn't automatically create splash screens so either you have to create it manually or use our PWA Assets Generator tool to create it automatically.
Branded splash screens display your app icon/logo with a custom background color. So we have implemented this feature in our PWA Assets Generator so all your required iOS splash screens are auto generated with a custom background color of your choice for your brand recognition.
