Knowledge is power

You know when you’re going through a dungeon and you see an item. What does it do? How does it work with what I have? Should I pick it up? Any question you have I’m pretty sure this app can answer for you. From cards to transformations. I haven’t had a question that this app couldn’t answer for me.

Some things I found useful: When you look at an item you can mark if you found it or not also on the characters you can mark what completions marks you have. If your new to this game or old there is something in this app for you. I open it as soon as I start the game every time.
I want to say thank you to the developers hugs and kisses because I love you guys!

Absolute must-have companion app

This app saves me so much time and trouble while playing Binding of Isaac: Afterbirth+. I usually like to just get the item and learn what it does the first time around, but with SO many items, it’s easy to forget what each one does.

It is so quick to search for any item or trinket you come across with this app. Being able to filter by the Item Pool one comes from is handy, but even better is the color sorting that allows you to quickly find the info you need and get back to the game.

I haven’t fully utilized it yet, but the ability to mark the items you’ve collected and bosses you’ve defeated seems like a great help to any completionist.

Developer Response ,

Thank you! I've also added a few improvements to the search in the latest updates, It should be even easier to find the item you are looking for using descriptive search. Make sure to check it out!

This is an amazing app, there is soooo much to it, it has everything you have ever wanted. This guide is very helpful for people with >200 hours of the game. I feel that the amount of effort put into this app is incredible! The app deserve to have 6/5 stars! The best part is that you can access EVERYTHING without adds! The app needs an option where I can just keep watching ads to support the developers, because they deserve it! But seriously there are almost no ads which is AMAZING! Is app is a instant D7/D6! (I didn’t even know the D7 was a thing until I got this app!) Everyone who likes TBOI needs to get this app!
