About this app

This app is a guide NOT the Game of The Binding of Isaac Repentance and Afterbirth + (Made by Edmund McMillen) I’m not him or related in any way. I’m just a fan.

The application includes the last Repentance update and Afterbirth +:
- All the items with a description, the statistics it can give and the pool in which it can appear.
- All Trinkets with description and how to unlock it
- Stats Calculator to see how it would affect picking up an item with a character and with what statistics it would remain (Beta)
- Pickups (Cards, Runes, Souls and Pills)
- Transformations with description and the items to obtain it
- Characters (Normal and Tained)
- Dice Rooms
- Bosses
- Enemies
- Achievements
- Some of the above include filters to make it easier to find what you are looking for

This is a great app. Easy to use and the UI is nice. Could use a section for room types. And this is mostly a wish, but I think a great addition would be keyword searches. There's like 12 battery items, but not all of them have battery in the title, so I have to look through all the items or guess the right word. Which is more Isaac's fault, really. Maybe the option to add and save keywords for items to make future searches easier. My brain can only hold so many roguelite item effects 😭

it's functional as it needs to be. I will say, not having a color filter that allows to find an item of unknown name much quicker. I'm having to meticulously scroll for the item, with hopes of not passing it. Color sorting allows me to find a red items in a fraction of the time. please add this, I didn't realize how much it helped until it was gone.

Amazing app, been using it for what I believe to be 2+ years, but it's still missing a few things- only one I can think of at the top of my head would be a way to see venders and stores like blood donation machine, all the venders, the reroll machine, etc. This is mainly to see drops, chances, and how to unlock them. Love the app though so thank you for it's creation.
