I wouldn't call the Cafit - fitness UI app kit outstanding, but I would say it does it's job very well. It's has a huge variety of concept screens all which coherently mash together to create a well thought out userflow. Also the color scheme really catches the eye with a muted orange and soft shades of grey.
