FinFlow

A reference mobile-product concept demonstrating the information hierarchy, consent patterns, and backend boundaries needed for a personal finance experience.

Financial activity can be difficult to understand when balances, recurring bills, and discretionary spending live in separate places or are only visible after the fact.

FinFlow brings a user’s cash-flow picture into a calm mobile dashboard, with explicit connection states, categorized activity, and forward-looking budget views.

• Cash-flow timeline and account overview
• Spending categories with user review controls
• Recurring payment detection concept
• Budget planning and upcoming-bill reminders
• Biometric app access and privacy settings

• React Native client with feature-oriented screens and secure local storage
• Backend-for-frontend API that separates mobile concerns from provider integrations
• Tokenized financial-data integration boundary; no credentials stored by the app
• Encrypted data in transit and at rest with least-privilege service access
• Event-based notification service for user-approved reminders
