Rad Pack (free version) is a theme that turns your phone or tablet into a gnarly retro 80's device with rad chrome looking icons and seriously choice 80's themed wallpapers. Each retro-looking chrome and hot pink icon and was hand crafted with a simpler time in mind; the 1980's.The chrome and neon pink icons are xxxhdpi which means they're super rad. It also means they're HD. Basically, the res is gnarly and super high qual.
You can manually edit icons in most launchers by long-pressing the icon you'd like to edit.
Widgets: If your widget stops updating, check your system or battery settings to make sure the app is exempt from battery optimization.
You may need a 3rd party launcher to apply the icon pack. If your stock launcher doesn't support icon packs, you can use apps like Awesome Icons or Unicon to change your icons without using a 3rd party launcher.
This is the free version of the app. Get the pro version here:
