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 (1.9.7.17) 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
- Bag of Crafting: enter your seed and the pickups you have to see everything you can craft with Tainted Cain. You can also search which recipes give a specific item, or pick the pickups you want to mix
- Collection: mark the items you already have and filter by collected or pending
- 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 Tainted)
- Dice Rooms
- Bosses
- Enemies
- Achievements, with the option to mark them as completed or pending
- Some of the above include filters to make it easier to find what you are looking for, including filtering and sorting the items by color
- Available in 12 languages: English, Spanish, Portuguese, French, Italian, German, Polish, Russian, Japanese, Korean, Chinese and Hindi
- All the information is inside the app, so it works without an internet connection

I don't like that I can't just type the name or what it says when you pick up an item to find said item. I think this app has too many unnecessary tabs. And even then, I can't find a section for active items, devil/angel rooms... it renders this app a bit useless. In the distant past, it used to work this way (search by keywords, no need to open a specific tab). Who ever made the decision to change it made a bad call.

Good app, but could use some improvement. like adding the room types and what bosses can spawn there, or a section for all the curses, and I can't find any of the mini bosses, the seven sins just don't exist in the bosses or enemies section. I swear these were all in an older version but are no longer in the current version, along with a feature to scan an item from your game screen and it pops up with the item description.

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 😭
