allexamshelper-tech/ExpenseTrackerApp ? reverse-engineered prompt

Build me a simple expense tracker app from this repo that feels polished and easy to use. I want to be able to add expenses, edit or delete them, organize them by category, see totals, and quickly understand where my money is going. A clean dashboard with recent transactions, category breakdowns, and monthly spending would be great.

Please use the existing project setup and wire up anything needed so it runs locally without guesswork. If the database pieces in the repo are meant to be used, connect them so expenses actually save and load properly. If the Gemini key is part of the intended app, keep that working in a useful way, like short spending summaries or simple insights, but do not overcomplicate it.

Make the app feel complete, with sensible validation, empty states, and a responsive layout. Add a small README update with clear setup steps if anything is missing. You can look up current docs online if you need to.
