Nice tool that I didn't know about and which will be added to my favorites in order to quickly access the data.
One idea that I want to propose is to enlarge the time period as 1 Month ago I find it limiting for me. I know (as I am a software tester) that there are performance constraints, but I think that getting over it you'll provide more economical value through the tool.
Keep up the good work and development of the tool!
