This is a screen shot from the recently launched hopstop ipad app that I designed. It was the #1 ranked free app in the Navigation category for a couple weeks (now it's #7).
It was my first ipad app design and I had a lot of fun doing it.
I'm not a graphic designer, so I struggle with creating logos. This one is very simple, and yes, the font is Klavika which is the basis for Facebook's logo, but I really like it.
If I ever do this for real, I would change the font and add more the to shield.
