Overview

Problem Statement

Diners and group expense sharers lack a simple, precise, and reliable method for splitting costs, leading to confusion, overpayment, and resentment. Current solutions (manual calculations, generic apps) are often inaccurate, time-consuming, and inflexible, failing to handle complex scenarios like unequal shares, custom items, or split payments. This issue demands a new approach that guarantees fairness, transparency, and ease of use across diverse expense contexts.

Solution

A user-centric mobile app that tackles the pain point of complex expense splitting. Its clean, clutter-free interface prioritises intuitive interaction, allowing users to add expenses, customise splits, and manage group bills with ease. The "nudge system" replaces awkward reminders with friendly notifications, fostering smoother communication and eliminating friction around collecting payments.

User Research

Survey

I put a list of carefully crafted questions relevant to the problem in a Google Forms survey and asked people for their inputs to identify the user pain points and their opinions on the existing solutions to know the most important features that they look for in a bill splitting application.

Wireframes

Here are some very basic paper wireframes I made just for reference and noting initial ideas. Several changes were made to these to get to the prototyping stage.

UI Design

Style Guide

The colour blue and its shades are used because it represents trust and loyalty which is the main idea of the application. This can also be seen in the logo which is a simplified variant of a handshake, a common gesture that signifies successful transactions.
