Button System Design - Habit Tracker

Button System Design for Habit Tracker App

The Platform & Context I selected a mobile habit tracker app as my platform because I'm passionate about designing interfaces that genuinely help people improve their lives. The habit tracking space requires thoughtful UX since users interact with these apps daily, often during vulnerable moments when they're trying to build better routines.

My Design Approach After analyzing user behavior patterns in habit-forming apps, I realized users needed clear visual guidance to distinguish between different action types. This led me to create a three-tier hierarchy:

• Primary buttons - I reserved these for life-changing actions like "Add Habit" • Secondary buttons - I used these for management tasks like "Edit" or "View Details" • Tertiary buttons - I designed these for quick actions like "Skip for Today"

Technical Specifications Size Strategy:

• Large (56px): For primary CTAs that need maximum visibility
• Medium (48px): For secondary actions in main flows
• Small (40px): For compact spaces and tertiary actions

Typography Choice: I chose Inter because I needed a typeface that remained legible at small sizes while feeling modern and trustworthy - crucial for an app people use daily.

Color Psychology: I selected blue (#007AFF) as my primary color after researching color psychology in wellness apps. Blue promotes feelings of calm, focus, and reliability - exactly what users need when building new habits.

State Design Philosophy I crafted five distinct states because I believe every user interaction deserves clear feedback:

• Default - Clean, approachable
• Hover - Subtle anticipation
• Pressed - Satisfying confirmation
• Disabled - Honest limitation
• Loading - Patient progress

Accessibility as Priority I ensured WCAG 2.1 AA compliance because I believe good design should be inclusive. Every color combination I chose maintains sufficient contrast, and I tested all buttons with screen readers to ensure they work for users with visual impairments.

Why This System Works Through this design, I solved several key challenges:

1. Reduced Decision Paralysis - Users instantly know which action to take
2. Built Trust - Consistent feedback makes the app feel reliable
3. Supported Daily Use - The system scales beautifully across different contexts
4. Promoted Inclusion - Accessible design welcomes all users
5. Enhanced Motivation - The blue palette psychologically supports habit formation

Personal Impact Creating this system taught me how thoughtful button design can genuinely impact people's lives. When someone successfully builds a new habit partly because the interface guided them clearly, that's the power of intentional UX design.
