Clearly AppViz is the winner. Provides nice charts and downloads 13 weeks of data to your desktop and provides a clear interface.
Heartbeat Signed up for this site. After I login I don't see anything. Not easy to use or figure out how to generate reports. It takes too much time than it saves. If you have a different opinion do let me know.
Tap Mini from TapMetrics. I watched the demo. It seems to allow import. I don't like the drilling into different levels to view my data.
