Better than the wiki a good 9/10 times!

I’ve been using this app for two months now, and I rarely ever go back to the wiki - Everything’s right here! I have noticed that there is some exceptional detail describing BOI’s complex ecosystem, and everything is organized real nice. Item interactions are also here and I LOVE THEM. Literally anything you need info on in Isaac, I would wager a bet it’s here and you will leave more informed than you would anywhere else. I also emailed him about the expansion REPENTANCE, and he said they will be working hard to keep the app updated as more info becomes available. My only criticism is there’s no searching option based on simple info like colors/shapes/etc. Anyways, EASILY worth the three bucks or whatever, hands down.

Hi, actually the app search features a descriptive search for every item except Repentance items (which I'll be adding soon).

So, for instance if you search for "red triangle" you will get "Godhead", "The Body" and "Angelic Prism" as results, searching for "Syringe" will get you all the syringe items in the game. Also searching only for color should show you all or most of the items in the game featuring the color you searched for.

Nevertheless I'm going to try to improve it
Thanks for the feedback!

Amazing but not Perfect (Still deserves 5 Stars)

I've been using this app to track my progress on the Nintendo Switch version of Isaac and it is amazing it has almost everything I could ever want, but just almost I have some problems with the app that kind of double as suggestions.


I think it would be nice to have a guide to the champion forms of enemies and what each color does.


When the settings for Antibirth are enabled your ”Collection” section doesn't include Antibirth Achievements, Items, Witness completion marks, or Characters. I'm thinking that it would be reasonable to add this content for when someone is playing Antibirth.

(Current Game Switching)

If you wanted to add the original BoI and BoI:WotL I feel it would make a more comprehensive guide. I don't know if it is possible, however, my idea is: Three sections one for ”Classic Isaac”, ”Repentance”, and ”Antibirth”

Classic | Repentance | Antibirth

Isaac | Rebirth (Branches off) -> Antibirth
WotL | Afterbirth | (Seperate
(Seperate)| AB+ | Data)
Data) | BP1
| BP2
| BP3
| BP4
| BP5
| Repentance

Developer Response ,

Thank you for your feedback! I'm planning on adding a section to explain enemy champions colors in the next updates.

I'm not planning on adding info about the original versions of the game, I'm 99% focused on preparing the app for Repentance, so I can release a stable update shortly after Repentance is released.

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!
