One of Android's greatest assets is its ability to house custom launchers, or home screen alternatives. The installation of a new launcher can completely rejuvenate the user experience and since there are so many available at the Play Store, every need and requirement is covered. Nova Launcher is among the cream of the crop and while the fully-stacked Prime version would usually set you back $4.99, you can snap it up right now for 99 cents (or £0.50 in the UK).
Subject of a recent update that brought several Android 7.1 and Google Pixel-esque features along with it, Nova Launcher Prime is a feature-heavy utility that seems to cover all bases. The fact that it's regularly updated in line with new versions of Android means you don't have to wait for the official OTA, which often takes a while to reach intended handsets (if at all).
The team behind Nova Launcher has a special announcement incoming, so it's possible that an entirely new version could be on the cards. While the price has dropped down to a dollar on more than one occasion before now, this is a great opportunity to fully enjoy one of the foremost third-party launchers in the game.
