Anyone who uses one of the launchers compatible with Pixel Icon Pack-Nougat Free UI (like Nova Launcher, for example) can apply all the icons automatically with a single tap. If you don't have a compatible launcher already, you can still change the icons, but you'll have to do it manually.
In the left drop-down menu, you can find a few very interesting additional options. On one hand you have a tool for requesting icons. On the other hand, there's a gallery of pretty wallpapers with the Pixel Launcher look, ready to be downloaded and applied to your home screen.
Pixel Icon Pack-Nougat Free UI is a great icon pack with an elegant presentation. Plus in general, the quality of the icons is really great.
Requires Android 4.0.3 or higher
