Hi Robert,
Apologies for the following info not being more obvious; will fix this asap.
Background
Rather than attempt to create our own common debugger we chose to implement the very best open-source debugging tools for the Android and iOS platforms. You just can’t beat’em. For Android GapDebug implements the Chrome Developer Tools. For iOS GapDebug uses the Safari WebKit Inspector. I found the following links buried in the user guide (will make it much more obvious asap).
Resources
Please see the following doc for using the debug tools specific to your mobile platform.
