AI-powered spending management iOS app with full Agent architecture for sale.
PiggyPal is a fully-built iOS AI spending management app targeting young adults in Australia. Built solo over one year, currently in TestFlight with 11 active testers. What makes this different from a generic expense tracker: Intent Router: A custom multi-signal weighted routing engine that classifies user input across expense recording, data queries, deep analysis, and casual conversation — in both English and Chinese. AgentEngine: A complete Agent loop with goal management, event evaluation, nudge generation, semantic deduplication, and adaptive cadence adjustment. This is not a chatbot wrapper. UserMemoryStore: Persistent cross-session user affinity memory that personalises AI responses over time. AIChatViewModel: Clean State/Actions/Reducer architecture with proper @MainActor isolation, debounce, and memory management. Tech stack: Swift Xcode Supabase (backend) DeepSeek API Apple Sign In TestFlight What's included in the sale: Full source code (documented, with comments) Supabase backend configuration Apple Developer App ID UI design assets and screenshots 30-minute handover call Revenue: Pre-revenue. Paid features built, not yet activated. Asking: $2,500 USD (negotiable).
Next step: <p>The most immediate next step is activating the paywall - everything is already built and configured at A$8.99/month. </p><p><br></p><p>From there: submit to the App Store, run targeted acquisition in Australia targeting young adults aged 18-30, and expand language support beyond English and Chinese. </p><p><br></p><p>The Agent architecture is extensible — a buyer could add bank account linking, receipt scanning via camera, or expand to other markets with minimal core changes.</p>

Reason for selling
I built PiggyPal as a solo project over 12 months while completing my Master's degree at the University of Sydney. The product is complete and the architecture is solid, but my focus is shifting to a new direction. I'd rather see it in the hands of someone who can take it to market than leave it sitting on TestFlight.
