Hue Config Viewer is a free Android app developed by life4hue. It is a utility tool designed specifically for Philips Hue system users who want to view and compare the configuration inside their Hue bridge. The app functions like a "registry viewer" and provides a detailed look into the configuration without allowing any editing or control over the lights.

The Hue Config Viewer displays the bridge configuration keys and values side by side in a horizontal layout. If the font size is too small, users can switch to landscape orientation for a larger font and more horizontal space. Changes made to the configuration are highlighted when the user retrieves the configuration again by tapping the sync icon.
