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

I love this app. I've been really into The Binding of Isaac for over a year now, and it's really been helpful to track my progress and learn about new items when I do the daily runs. Also the dice rooms. The only thing I would say would improve it and make it perfect would be if there was a counter to tell you how many achievements you have out of the total amount. But otherwise absolutely adore this!!! This app has made my game play MUCH easier.

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.

Ive had a pretty good overall experience with this, the loading takes just a second or so but im usually not in a rush, the only thing that would be great is if you had the capability to click an item and add it to your game time profile, and when you come across another item you can cross reference its synergy with the items you have. Idk if i explained that in a good way but just a quick reference to see if i have these items if this item would work well or not.
