100 Days of UI is a daily challenge sponsored by dailyui.co. The prompts, which you can see next to each design below, are purposefully brief and open-ended, allowing for maximum creativity. I chose to complete each in mobile because I enjoy designing for mobile most — I like the extra challenge the minimized screen real estate provides. I have chosen a selection of my favorite designs to share.
