We had already commented on another article in January (iOS 10.3 will allow apps to have an alternative icon) and now it has come true. App Store applications may offer an icon change, if the user wishes. The first to show what this looks like in real life are the MLB and NHL sports apps.
Both now allow the app icon to have the team symbol the user supports. Just enter the settings and choose the icon for your team.
The choice will depend on the developer, who will make customization available or not. Only adapted applications will offer the possibility of changing the icon.
And then? In what other types of applications do you think this function can be useful? Give your idea here in the comments. ?
