This is my logo design for 
The idea:
The idea behind the design is a play button at the edge of a clock to show that the clock is reading the play time. The bar chart at the centre of the clock represents statistics. I tried as much possible to let the logo really say much about. "YouTube Watch History Statistics Viewer"
The logo is scalable and will look pretty good at any scale, no matter how small.
