Mixt is a free Android app developed by Massive Papaya that allows users to create and apply custom color gradients as their phone wallpaper. The app is completely ad-free and straightforward to use.

To create a gradient, users choose two colors of their choice from a color picker and Mixt generates a smooth gradient between them. The app also provides tips for best results, such as choosing colors close to each other or the same color with different brightness. Users can save their gradients and apply them as wallpaper directly from the app.

Mixt is developed with love in Thessaloniki and offers a unique way to personalize your phone's wallpaper. However, it should be noted that when applying a saved gradient image from your gallery, it's best to use a third-party app like QuickPic to avoid image compression and gradient banding.

Permissions required by the app include read and write external storage for saving the wallpaper to the device, set wallpaper and set wallpaper hints for taking the right dimensions of the screen, and vibrate for touch feedback.

Overall, Mixt is a great app for those who want to add a pop of color to their phone's wallpaper without any hassle.
