Guide with little room for improvement

This guide is near perfect With small thing that are quality of life improvements everywhere, but there is a few things that would put the cherry on top, save files, champion guides, and antibirth curses and collection

there are save files in the game so you should make it in the app, for example I play on switch and I’m thinking of getting the game on ps4 so it would be nice if I could just switch to a different save file just quality of life thing but it would help a lot.

After over 200 hours in gameplay I know the champions but it would of been a lot easier to know them from the start. (Including the champion that heals other enemy’s)

Antibirth curses don’t show up on the curses page however they are a new thing only in antibirth. It would also be nice to have antibirth on the collection page to collect if people play antibirth this should be a setting though because people might just want to see what’s in the mid and what will probably be in repentance.

One extra thing when repentance get released how soon do you plan on updating the app, because I don’t have a debug console in my possession so I can’t test out ideas for synergies or just plain old items on there own and Edmund says this will be the biggest Isaac dlc so I’m kinda relying on this guide to help me out.

Thanks for reading this review thanks for the amazing app and guide.

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!
