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.
