Vibrant Grocery App UI Revamp

I’m giving the Monita Food & Grocery mobile app a fresh coat of paint across both iOS and Android. Around 13–15 screens—think splash, onboarding, home, product detail, cart, checkout, and order tracking—need to be rebuilt so they feel modern, lively, and on-brand.

The main objective is clear: modernize the look while keeping every interaction slick and intuitive. I already have a detailed branding guide, so you’ll have color palettes, typography, and iconography at hand. What I want from you is a vibrant, colorful interpretation of those assets that feels consistent across the entire flow.

Here’s how we’ll work:
• You’ll translate each existing screen into high-fidelity designs (Figma or XD preferred) that meet current iOS and Material Design guidelines.
• Once designs are locked, implement them in the live codebase, ensuring pixel-perfect rendering on recent iPhones and popular Android devices.
• All existing functionality—API calls, cart logic, payment, etc.—must remain intact; this is a purely visual overhaul.
• Handover includes updated source code, design files, and a short style-sheet summarizing reusable components for future iterations.

If you’ve shipped colorful, consumer-facing apps before and can move quickly without losing polish, I’d love to see your repo or store links and jump right in.
