MyFinanceApp – Personal Finance OS
Native Android financial management app with offline-first architecture, PDF receipts, and full transaction tracking.
Project Overview
MyFinanceApp is a native Android application designed to serve as a complete personal and business financial operating system. It provides real‑time financial insights, transaction management, PDF receipt generation, and full data export – all stored locally with Room (SQLite) for offline‑first reliability.[reference:2]
The Challenge
Users needed a reliable, privacy‑first financial tool that could:
- Track income, expenses, and financial runway in real time
- Work entirely offline – no cloud dependency
- Generate professional PDF receipts and statements
- Provide dynamic category and subcategory filtering
- Offer full data management (delete by date range, export statements)
The Solution
We built a modern Android app with a clean architecture:
- Kotlin – modern, concise, and safe language
- MVVM + StateFlow – reactive UI with predictable state management
- Room (SQLite) – local database with offline‑first reliability[reference:3]
- Material Components – clean, intuitive UI following Material Design[reference:4]
- PDF generation – professional receipts and full financial statements[reference:5]
