The Daily UI Challenge is a 100-day challenge sponsored by dailyui.co. Each morning I woke up with a new UI design problem to solve in whatever way I saw fit. The prompts are purposefully brief and open-ended, allowing for maximum creativity. I chose to complete each in mobile size because I enjoy designing for mobile most — I like the extra challenge the minimized screen real estate provides and I like to think doing so stretches my abilities and skills. I have chosen a selection of my favorite designs to share below.

Mobile mock ups of site


Design a credit card checkout form or page. Don't forget the important elements such as the numbers, dates, security numbers, etc.

Checkout screen

User Profile

Design a user profile and be mindful of the most important data, names, imagery, placement, etc. Is it for a serious profile? A social profile?

Checkout screen


Design a calculator. Standard, scientific, or specialty calculator for something such as a mortgage? Is it for a phone, a tablet, a web app?

Checkout screen


Design settings for something. Is it for security or privacy settings? Game settings? What is it and what's important?

Checkout screen

Landing Page

What's the main focus? Is it for a book, an album, a mobile app, a product? Consider important landing page elements (call-to-actions, clarity, etc.).

Checkout screen

404 Page

Design a 404 page. Does it suit the brand's style? Is it user-friendly?

Checkout screen

Music Player

Design a music player. Consider the controls, placements, imagery such as the artist or album cover, etc.

Checkout screen


Design a Countdown Timer. Is it for an app? An interface for an oven? A sport related countdown? A launch countdown for NASA?
