Expense Tracker App Prompt for NiuNiu
Ask NiuNiu to build a private Android expense tracker with manual entries, categories, monthly totals, filters, and CSV export.
Prompt
Build an Android expense tracker where I can add expenses, choose a category, add notes, see monthly totals, filter by category, and export records as CSV. The app should store data locally on my phone where practical.
What NiuNiu will plan
- Add expense screen with amount, category, date, and notes
- Monthly summary with category totals
- Search and filter views
- CSV export for personal records
- Local storage for entries and categories
Local-first notes
- Manual expense entries, categories, notes, and summaries can be designed for local storage.
- Bank feeds, AI spending summaries, cloud backup, or multi-device sync would require external services.
Useful variations
- Add recurring expense templates.
- Show a cash-flow chart by month.
- Add separate personal and business categories.
Before approving the build
Review the generated plan, credit estimate, data storage choices, and any external services before implementation starts. For private personal apps, ask NiuNiu to keep records local where practical.
