Redesign Android Travel App UI/UX

UI/UX Redesign for Android App — TrypBuddy (Expense Splitting App)

I'm looking for a talented UI/UX designer to redesign my published Android app, TrypBuddy, a group expense-splitting and bill-sharing app for travelers.

About the app
TrypBuddy helps friends, families, and colleagues split trip expenses, track shared spending, and settle up fairly — online or offline. It's live on the Play Store:
https://play.google.com/store/apps/details?id=com.trypbuddy.app

What I need

• A modern, clean, and intuitive redesign of the existing screens
• Improved user flows for creating trips, adding expenses, and settling up
• Consistent design system (colors, typography, components, spacing)
• Light & dark theme variants with customizable accent colors
• Support for a scalable layout (app is available in 10 languages, including RTL for Arabic)
• Screens include: onboarding, trip creation, expense entry, "who owes whom" summary, checklist, budgets, and profile

Deliverables

• High-fidelity mockups (Figma preferred)
• Complete design system / component library
• All core screens in both light and dark modes
• Editable source files

What I'm looking for in you

• Strong portfolio of mobile app redesigns (fintech/expense/travel apps a plus)
• Solid grasp of Material Design principles
• Attention to usability, not just aesthetics

Please share your portfolio, your estimated timeline, and your quote when applying.
