I like the variety of integrations and the fact that they plan to keep expanding on them.

There are so many integrations! In the past I have had to pore over spreadsheets and various analytics type accounts, trying to figure out how to best export data and then how to display it along side other data in the spreadsheet. GreyMetrics pulls in all the data I could ever want from every tool and service I have ever used. Fantastic!

GreyMetrics is fast and simple to use. In less than three minutes I was able to connect to Facebook and Google Analytics and generate a report. That's just not possible doing it manually or with more complex tools.
