Moneymind — AI-Powered Personal Finance App

Description

Moneymind — AI-Powered Personal Finance App

Moneymind is an AI-powered personal finance app you can actually
ship
— a Flutter mobile app on a Firebase backend, sold as clean, production-grade
source code. Unlike the “AI finance” templates that are just UI
mockups, Moneymind’s AI is wired up and functional: a
receipt scanner, a finance coach, spending forecasts, smart categorization,
anomaly detection, a health score, and budget/savings generators all run for
real — behind a dual OpenAI + Gemini backend, server-side, so
no AI keys ever ship in the app.

It’s offline-first (Drift/SQLCipher on-device is the
source of truth, Firestore reconciles) and
single-user personal finance — one person tracking their own
money. Not multi-user, family, or a marketplace.

Quick setup

1. Install deps: pnpm install (repo root) and
   flutter pub get in apps/mobile.
2. Wire your Firebase project: flutterfire configure from
   apps/mobile.
3. Set the 5 Function secrets, then deploy Firestore rules, indexes, storage,
   and functions.
4. (If you change models) run build_runner with
   --delete-conflicting-outputs.
5. Run the app and sign up.
6. Publish the Remote Config keys (RevenueCat, AdMob, free-tier ceilings,
   prices).
7. Configure app signing, then build releases for Play Console / App Store
   Connect.
8. Optional: deploy the admin panel —
   pnpm -F admin grant-admin you@example.com --create, then import
   the repo on Vercel with root directory apps/admin.

In-app pricing

The in-app Premium subscription ($4.99/mo · $29.99/yr ·
$79.99 lifetime, via RevenueCat) is what the app’s end users pay — you
keep 100% of that.

Changelog

1.1.0

• New — admin panel — an optional Next.js 16 ops console
  (apps/admin): dashboard, users, AI usage & cost, a
  validated Remote Config editor, billing, system health, audit log, and
  access control. Gated by a Firebase Auth custom claim, read-only demo mode
  included, and every read is server-side so your security rules stay
  unchanged.
• New — admin backend — an
  aggregatePlatformStats daily scheduler, plus a monthly usage
  rollup, to feed the console (18 Cloud Functions total).
• Deployment — the admin panel now deploys on
  Vercel (documented end to end), with a container /
  Cloud Run path also supported.
• Android release build — explicit
  compileSdk 36, release signing read from a gitignored
  key.properties with no debug fallback, and R8 minification +
  resource shrinking with keep rules.
• Fixes — core library desugaring for local notifications;
  re-login onboarding, form validation, wallet restore, and month-summary
  corrections; Apple Sign-In shown on iOS only.
• Packaging & security — the seller’s Firebase
  config no longer ships in the buyer zip, and the packaging step now scans
  tracked files for secret-shaped values before building.
• Docs — a full app-signing section and the admin-panel
  setup guide.

1.0.0 — Initial release.

Moneymind is a personal finance app for individuals who want a clearer view of their day-to-day money. It lets users record expenses, manage budgets, set savings goals, and review spending through reports and charts. Its AI features can scan receipts, sort transactions into categories, identify unusual spending, forecast upcoming costs, and provide guidance through an in-app coach. It also supports recurring payments, debts, multiple currencies, and account security features such as PIN or biometric locking. It is designed for one person managing their own finances, rather than shared household or business accounts.
