AI Chat-Based App UI/UX Design

I'm seeking a skilled UI/UX designer to create a mobile experience for an AI-powered chat-based personal assistance app, targeting adults on both iOS and Android platforms.

We’re building a chat-based mobile app powered by AI. The app provides expert, real-time guidance through a conversational interface (text only — no video, no audio). We’re now looking for a talented UI/UX designer to design the mobile experience from scratch.

This is not a data-logging or tracking app — the main focus is on creating an engaging, intuitive, and visually clean chat-based interface for iOS and Android.

Key requirements:
- Design an intuitive, engaging, and user-friendly interface
- Create seamless navigation and interaction flows
- Develop a cohesive visual identity that aligns with the app's purpose
- Collaborate closely with our development team to ensure design feasibility

Ideal Skills and Experience:
- Proven experience in mobile app UI/UX design
- Strong portfolio showcasing similar projects
- Proficiency in design tools such as Sketch, Figma, or Adobe XD
- Understanding of user-centered design principles
- Excellent communication and collaboration skills

What You’ll Design:
• Splash / Welcome screen
• Sign-up & login screens
• User onboarding flow (step-by-step or conversational)
• Persona selector (user chooses AI tone/coach)
• Main chat interface (core screen)
• Prompt/Check-in screen
• Premium upgrade screen
• Payment flow (mockup only)
• Settings screen (basic profile options)
• First-time chat view
• Error states (e.g. no connection, timeout)

Around 10–12 unique mobile screens.

Style We Want:
• Clean, minimal, mobile-first
• Friendly and modern
• Easy navigation with low friction
• Optional bonus: dark mode design

Your expertise will help us deliver an exceptional user experience. Looking forward to your proposals!
