The Google Analytics Reporting suite is an Adobe AIR application that brings Google Analytics to the desktop. It uses it’s own custom API to interact with Google and nearly implements all features of Analytics.
It obviously requires the Adobe AIR framework to be installed first, but I’ve found it to be a great tool … even if it is still in beta and has a few, erm … undocumented features.
The main thing I’ve spotted so far is that when opening the application you’re invited to “Select a profile to continue”, only none are presented until you click “Manage profiles” and then hit the “Back” button.
It’s a minor niggle, there is a workaround and I’m sure they’ll fix it in due course (now that it’s been reported).
As far as using it, I’ve found it to be significantly faster and more responsive than using Google Analytics via a browser, which has to be a good thing.
It’s certainly worth checking out.
