What a steal: you can get Nova Launcher Prime for $0.99 in the US, even cheaper in other countries
Good news, customization junkies! Arguably the best custom launcher for Android, Nova Launcher Prime, has been discounted as a part of its developer's holiday promotion campaign. You can get it for $0.99 stateside, down from the regular $4.99, but users in other countries can get it for even less - recently Google slashed the minimum app prices in 17 countries, so you can get Nova Launcher Prime for way less than a buck.
As some of you might be aware, Nova Launcher is also available in a non-Prime flavor, which can be snatched for free from the Google Play Store. Why would you want to get its paid variation then? The free version comes with most of the bells and whistles that the premium version flaunts, but some important ones are missing. For instance, you can't meddle with the size of the icons or the home screen grid, which are kind of important customization features. Nova Prime also allows you to assign different gestures, create folders and groups in the app drawer, and hiding apps from the app drawer, among other features.
