NUS Computing Orbital 2022

Saturday is a mobile only, computer vision enabled smart personal accountant.

Motivation

Through our personal experience of having lived on campus for the past year, we have noticed the tedious nature of settling shared bills.

Currently, the most common method of settling shared debts is individually calculating and spelling out the split of expenses through Telegram messages.

This is not only inconvenient, but it also lacks a measure of accountability to verify that the requested sum is computed and paid correctly.

As a result, we feel that there is a need for a platform that allows users to easily track, account for, and compute splits.

Aim

Through a unique mobile application that organizes and tracks bill splits, we hope to provide a platform for students to better manage their personal finances.

User Stories

• As the creditor that initially paid for the bill, I want to be able to split the bill accurately without having to do the computations myself.
• As the creditor that initially paid for the bill, I want to be able to track who has and hasn’t paid me back.
• As the debtor, I want to be able to view the breakdown of the sum requested from me.
• As the debtor, I want my creditor to be notified with proof that I have paid.
• As the debtor, I want the payment process through various financial services to be seamless. (link to DBS Paylah!, Google Pay, etc.)

Features

A robust user account system, accountability measures, and an automated splitting mechanism will be the 3 key features of the mobile application.

User Account System

• Ability to add friends
• Shows a breakdown of debit and credit by friends
• Auto-balances debit and credit amounts across friends (Nett amounts are displayed where possible)
• Tracks and displays a breakdown of expenses for the month
• Able to view payment request history for user error failsafe measures

Automated Splitting Protocol (ASP)

• Recognises items and their corresponding prices from an uploaded bill with computer vision (Implement IOS Live Text)
• Drag & Drop Cart Split functionality to allocate items accordingly

Accountability Measures

• Notifies a debtor when a creditor has requested for money
• Debtor can view and verify the request
• Weekly notification updates to collect and/or payback monies
• Notifies a creditor when a debtor has paid back money
• Creditor can view and verify the payback
