iOS Live Debugging tool - runs as part of your app

Nuimbus is a debugging tool for quickly understanding the current state of your application.

When added to an application, it will insert a paged scroll view beneath the status bar that contains any number of pages of information. These pages can show anything from graphs of current memory usage to console logs to configuration settings.
