The Witcher 3: Unofficial App is a companion app designed to enhance your gameplay experience in The Witcher 3: Wild Hunt. Developed by Jon Fulton, this free app is available for iPhone users.

One of the main features of this app is the Bestiary, which allows you to browse through all the monsters that reside in the world of The Witcher 3. You can read about them, learn their weaknesses, and apply your newfound knowledge in the game to gain the upper hand.

Another useful feature is the Alchemy section, where you can search through a comprehensive list of Bombs, Oils, Potions, and Decoctions. This helps you find the right one to give you the edge in battle. The app also provides a list of ingredients for each item.

Additionally, the app includes detailed maps of The Witcher 3, including locations added from both DLCs. While it does not reveal the location of special items of interest like the Witcher gear, it does contain the locations of all the main points of interest as seen in the in-game map.

Please note that The Witcher 3: Unofficial App is not an official product of CD PROJEKT. It is an unofficial companion app created by a fan for fellow players.
