Prompt template
Budget app prompt — copy, paste, build
A prompt for a native personal-budget app — monthly category limits, transaction logging, progress rings, and end-of-month insights. Designed for offline-first use so the app feels instant before any backend exists.
The prompt
Build a native iOS and Android budget app with: (1) onboarding to set monthly income and pick five starter categories with limits, (2) a home tab showing current month spend vs total budget as a progress ring plus a per-category list with mini progress bars, (3) an "add transaction" sheet with amount, category, date, and note, (4) a transactions tab with grouped-by-day list and a search filter, (5) an insights tab with month-over-month bar chart and top three overspent categories, (6) a settings screen for currency, month-start day, and category management. Use Expo, React Navigation, twrnc for styling, AsyncStorage for offline-first state, and Victory Native for charts. Default to a quiet light-mode design with one accent color.

Why this prompt works in AppGenie
Budget apps need correct math more than novel UI. AppGenie's A6 validator runs static checks on category math and rollover logic before the preview, catching the "off-by-one when the month rolls over" bugs that usually leak into production.

Expense tracker
A prompt for a focused native expense tracker — fast entry, category tagging, receipt photos, and a weekly summary. Designed for solo users who want a daily-spend log, not a full budget engine.

Expense splitter
A prompt for a Splitwise-style native app: trips, group balances, even and uneven splits, and settle-up. Designed to keep the data model crisp so AppGenie's validator does not bounce the build.

Trip planner
A prompt for a native trip-planning app — multi-day itineraries, per-day activity blocks, packing lists, and an offline map view. Designed to keep the data model crisp so the A4 architect plans clean trip and day entities on the first run.

Does the budget app sync with my bank?
No. The Pro variant scaffolds CSV import as the integration point. Direct bank sync (Plaid, TrueLayer) requires your own credentials and is left as a follow-up prompt.
Can I roll unspent budget into next month?
Ask "add per-category rollover so unspent budget carries to the next month." The diff-aware pipeline patches the rollover logic without touching the transaction screen.
