Modern UI Overhaul For Completed App

My mobile app is functionally ready for launch, but the interface still looks like an early prototype. I want a fresh, modern makeover that follows current design trends and elevates the overall user experience.

You’ll receive a fully working build along with screenshots of every screen flow. Your task is to redesign those screens—rethinking layout, typography, colour palette and micro-interactions—so the product feels polished and consistent from onboarding to checkout. I’m open to your creative direction on colours and visual style, as I haven’t locked anything down yet.

The final hand-off should include:
• High-fidelity mock-ups for every existing screen (Figma or Adobe XD is fine)
• A compact style guide covering colours, fonts, iconography and states
• All export-ready assets (SVG/PNG) organised by screen and density
• Notes or prototypes that clearly show animations, transitions and component behaviour

Once the design is approved I’ll pass it straight to my developers, so clarity and systematic naming are important.

If you have a portfolio that demonstrates clean, contemporary app design, especially projects where you refreshed an already-built product, I’d love to see it.
