A smart expense sharing and tracking app designed for everyday simplicity

Overview

Bubi is a mobile application designed to simplify expense sharing and tracking between individuals and groups.

The goal was to eliminate confusion around shared expenses and create a clear, transparent system that users can rely on in their daily lives.

My Role

I led the UX/UI design of the application, focusing on creating a simple and intuitive mobile experience.

From user flows to final interface design, I worked on reducing friction and making complex calculations feel effortless for users.

The Problem: Manual Tracking & Confusion

Managing shared expenses manually often leads to confusion, miscalculations, and lack of transparency.

Users struggled with:

I designed a system that makes expense tracking simple, clear, and automatic.

Key improvements included:

• Real-time balance tracking for each user
• Smart expense splitting logic
• Clear visual summaries for quick understanding
• Simple input flows to reduce friction
• Mobile-first design optimized for daily use

The Outcome

The final product delivers a clean and intuitive experience that removes the complexity of managing shared expenses.

Users can now track, split, and manage their expenses with confidence and ease.
