Project Introduction
In this modern digital age, most daily transactions are electronic. People are less aware of their financial situation without the sense of spending real cash, possibly worsening their abilities to control their assets. This app aims to tackle this issue by providing an all-in-one platform to record and plan finances in a user-friendly interface. Combined with the potential of machine learning, users can predict their future spending with a number of regression models.
This app can add, display and search for past income and expense records with labels assigned to transactions, then predict using stored record data.
Methodology
| Frontend (React Native) | – Can deploy to both iOS and Android platform in one code base – Provide native components for intuitive experience and outstanding performance |
| Backend (Express + node.js) | – Easy to set up server for connecting frontend and Retool – Robust and minimal framework |
| Database (Retool) | – Complimentary SQL database with simple and user-friendly UI – Singular remote database eliminates table conflicts |
| Regression Models | – Three regression models: Linear, Quadratic and Exponential for optimal prediction performance in all trends |
Final Results
| Home Screen | – Entry point to application – Check for recent transactions and total balance – Can sort or filter transactions by their attributes |
| Add Screen | – Use to add a new income / expense transaction for tracking – Support recurring transactions – Can specify name, amount, time and category of transaction |
| Trend Screen | – Use to predict future spending based on stored record – Can specify how long to project and transaction attribute applied |
