CleanUI

CleanUI is a launcher that can give your Android a 'flat style,' typical of the iOS interface. Unlike many other similar apps, this one doesn't have any ads at all.

In addition to being ad-free, CleanUI offers everything a good launcher should have if it wants to imitate iOS. By sliding down from the top of the screen, instead of the classic status bar from Android, you see an imitation of the iOS status bar. Likewise, if you slide up from the bottom, you see the respective iOS menu. Both menus are a convincing and attractive imitation of the iOS style.

As to be expected, all icons are the same as you'd find on iOS device, including the four docked at the bottom of the screen, which you can customize. You can also customize many other elements, including the wallpaper.

CleanUI is, without a doubt, the best iOS-style launcher for Android. What's more, it has an interesting extension called iOS7/8 theme for CleanUI, that can give the launcher an even more modern look.
