FAQ

What is this app?

This app is an unofficial guide for the game The Binding of Isaac: Rebirth and all its DLCs, including Afterbirth, Afterbirth+, Repentance, and the Antibirth mod. It provides a comprehensive database of in-game elements.

How can I identify items in the game?

You can identify items in two main ways: by using your device's camera to scan them, or by utilizing the advanced search feature which allows for aspect tag searches (e.g., 'green mushroom') and various filters.

What kind of information does the app provide?

The app offers detailed information on a vast array of game elements, including items (with synergies and interactions), trinkets, cards, pickups, achievements, transformations, characters, bosses, monsters, and much more. It also covers game mechanics like curses, floors, and item pools.

Is this app free to use?

The app is free to download and use, but it does contain in-app purchases and advertisements. These may offer additional features or a more streamlined experience.

What are the benefits of using the advanced search and filters?

The advanced search and filters allow you to pinpoint specific items or information quickly. You can filter by game version, item type (Active or Passive), collection status, pool type, and even search based on visual descriptions, making it easier to find what you're looking for.
