This tool helps you track progress in The Binding of Isaac: Rebirth by showing you which achievements you haven't unlocked yet.

The Percentage (%) column shows the percentage of players that have unlocked that achievement.

The Character and Boss columns show the character or boss required to unlock that achievement.

This app is inspired by Rebirth Achievement Helper and uses data from the Rebirth Wiki.

This website uses your browser's local storage functionality to keep track of your Steam API Key, Steam ID, and Binding of Isaac Steam achievement data. This is automatically stored on your device and is not transmitted to any server.

Your Steam API Key is sent directly to Steam's servers to fetch your achievement data — it never passes through our servers in a way that we can store or read it.
