# Unlocking the Dex

The Dex is a key app in your journey. Accessible from your phone (📱 icon in the top-right corner of the screen), it lets you view the history of all the Data you've encountered or captured.

#### 🔓How to unlock the Dex:

1- Head to **Javerdale City**, located north of your starting point.
