Lightning Launcher isn’t the most popular but it does have among the highest ratings. This Android launcher app has a very simple premise. It aims to use as few of your device’s resources as humanly possible. The features are a bit scant but do include some powerful ones including unlimited home screens, the ability to add and arrange icons anywhere you want, and its ability to run on almost nothing makes it a great launcher for older and lower end devices. It’s definitely worth a shot if you need something light and fast.
