Awesome! At Fileboard we use lots of third party tools (Mixpanel/KISSMetrics) to keep track of user metrics and stuff but there are always things where these tools just can't provide us with answers. Especially since we are an ipad app and most of these things are designed for web app usage.
I didn't want to roll my own solution for keeping track of the "extra" stuff but having seen this I am definatly going to give it a spin and see wether it helps us get more grip on user behavior.
Thanks for sharing!
