Kanai's Cube, an unofficial app developed by MixBexApps, is a simple lifestyle app available on Android for free. It is a basic preview of all the Legendary Powers that players can extract and a list of all the recipes and materials needed for Kanais Cube.

For those who play Diablo 3, Kanai's Cube was added in the game's ROS Patch 2.3. It provides players with the ability to convert or break down legendary items and gain bonuses from their special properties. Obtaining the cube requires players to head to the Kanai's Throneroom, which is located on level two of the Ruins of Sescheron in Act Three.

Using this app, players can keep track of what they have extracted so far to avoid wasting materials in the next season. However, it is important to note that this app is not provided by Blizzard Entertainment and the graphics used in the app are the property of Blizzard Entertainment.
