One of the great benefits of Android is that you can change the entire look and feel of your device in an instant by installing a launcher. The two common drawbacks, however, are that many launchers claiming to be free often require in-app purchases to unlock the best features, and some launchers are so bloated they can make your device feel sluggish. Lean Launcher addresses both of these problems. It’s open source – so ‘ free’ genuinely means free – and, as its name suggests, it’s a lightweight install. It provides a smart, sophisticated, customisable, stock Android-like interface with notification dots, Google Now and dynamic shortcuts on support devices.
