Time to make your app dreams come true! You're about to transform your amazing design ideas into a real, interactive prototype that people can actually tap and use. This is where the magic happens - your app is about to come alive!
- Estimated Time: 12-15 hours across 4-5 sessions
- Difficulty Level: ⭐⭐⭐⭐ 4/5 stars
- Team Size: Individual or pairs
- Deliverables: Interactive mobile prototype, design system, user flow documentation
Objective: Create an interactive mobile app prototype based on your design concepts from Lesson 12
What You'll Learn:
- How to transform design concepts into functional prototypes
- Interactive design principles for mobile apps
- Figma prototyping tools and techniques
- User flow implementation in digital format
What You'll Create: A functional, interactive mobile app prototype that brings your app concept to life
Your journey to prototype mastery includes these exciting achievements:
- 🖼️ Screen Builder: Create beautiful, functional app screens
- ⚡ Interaction Master: Make buttons, links, and forms actually work
- 🔄 Flow Designer: Connect screens with smooth transitions
- 🎨 Visual Wizard: Apply consistent design across your entire app
- 📱 Mobile Genius: Optimize everything for perfect mobile experience
You will be creating an interactive prototype for the mobile app you designed in Lesson 12. This prototype should bring your design concepts (logo, colors, typography, and interactive elements) to life through functional screens and user interactions.
Follow this video example to learn how to prototype:

Important: Make sure you develop your own app prototype based on the app you created in Lesson 12.
Your prototype should include:
- Welcome/onboarding screen
- Main navigation/dashboard
- At least 3-5 key feature screens
- User profile or settings screen
- Clickable buttons and navigation
- Form inputs and interactions
- Smooth transitions between screens
- Touch-friendly interface elements
- Clear navigation paths
- Logical screen progression
- Back/exit options
- Error states or feedback messages
- Consistent color scheme and typography
- Appropriate imagery and icons
- Mobile-optimized layouts
- Professional appearance
- Apply your logo design from Lesson 12
- Use your chosen color scheme consistently
- Implement your selected typography
- Apply your button and interactive element designs
Here's what the pros know about creating amazing mobile prototypes:
- Start with wireframes: Sketch your screens on paper first - it's faster than jumping straight into Figma!
- Think with your thumbs: Design for how people actually hold and use phones
- Test early and often: Click through your prototype yourself before showing anyone else
- Keep it simple: Better to have fewer screens that work perfectly than many that feel confusing
- Make it feel real: Add micro-animations and transitions to make your app feel alive
- Design for different screen sizes: Your app should look great on both small and large phones
Document your process:
- Screenshot your key app screens and design system
- Write 2-3 sentences about your design decisions and user flow choices
- Note any challenges you overcame in mobile interface design
- Save your prototype link and process documentation
- Find a review partner
- Present your mobile prototype and demonstrate key interactions (5 minutes)
- Listen to their feedback without defending your design
- Take notes on usability and visual design suggestions
- Ask clarifying questions about mobile user experience
Use "I like, I wish, I wonder":
- I like: What works well in the mobile interface
- I wish: What interactions or visual elements could be improved
- I wonder: Questions about user flow and mobile usability
- Choose 2-3 suggestions to implement in your prototype
- Document what you changed and why
- Thank your reviewer!
This project mirrors real work at companies like:
- Mobile App Development: Companies like Instagram, TikTok, and Uber rely on mobile-first design thinking
- Product Design Teams: Apple, Samsung, and Google create mobile interfaces for millions of users daily
- Entry-Level Role: Mobile UI Designer or Junior UX Designer
- Salary Range: $50,000-70,000 for entry-level mobile design positions
"Mobile design is about understanding how people naturally interact with their devices. Every tap, swipe, and gesture should feel intuitive and purposeful."
- Marcus Kim, Lead Mobile Designer at Spotify
Make sure to complete all tasks and double-check your project before submission:
- Ensure your prototype is interactive and functional
- Test all navigation paths and interactions
- Verify visual consistency across all screens
- Include your design file or prototype link if requested
- Review that your prototype matches your Lesson 12 design concepts
Use your Lesson 12: Design Concepts work as the foundation for this prototype. Your logo design, color scheme, typography, and interactive elements should guide your prototype development.
You will be using Figma to create your interactive prototype.
