1. Product Overview

MyExpenseTracker was architected by AppQor to solve the biggest pain point in modern consumer finance apps: forced cloud bank linking and subscription lock-in. Built with an encrypted local SQLite persistence engine and fluid multi-currency support, the suite empowers individuals and freelancers to track daily expenses, recurring bills, savings goals, and category budgets with zero network latency.

2. Engineering Objective

Deliver a sub-15MB mobile financial companion that operates 100% offline with optional encrypted backup, instant optical receipt extraction, and interactive monthly cashflow forecasting.

3. Measurable Outcome

Achieved 99.6% crash-free sessions across Android 14/15 and iOS 18 devices, 60 FPS chart scrolling across 50,000+ ledger rows, and full compliance with Google Play Financial Features and Data Safety policies.
