FinPrint by Fynx

Inspiration

Money apps usually stop at tracking. We wanted FinPrint by Fynx to go further and explain behavior, patterns, and actionable next steps so users can make better decisions, not just view numbers.

What it does

FinPrint helps users:

Track and manage expenses in one place
View full expense history
Edit and delete expenses
See Money DNA insights from spending trends, category patterns, and budget context
Use an AI Financial Coach for personalized saving guidance
Set income-based budget and savings goals

How we built it

Backend: Python + Flask APIs Database: SQLite for users, expenses, and coaching history Frontend: React dashboard with tabbed views (Dashboard, My Expenses, Money DNA, Coach) Integrations: AI services for categorization, narrative insights, and coaching - Backboard.io, Gemini AI APIs

Challenges we ran into

Keeping insights meaningful with mixed historical + real-time user data Integrating third-party AI endpoints with unclear/changed API paths and methods Handling fallback behavior when external AI providers are unavailable

Accomplishments that we're proud of

Built a complete end-to-end personal finance experience Added Money DNA with visual, goal-oriented insights Delivered a working coaching experience with practical recommendations Improved UX by separating concerns into focused tabs

What we learned

Reliable API integrations require exact endpoint/method/auth specs Finance products need both data correctness and clear storytelling Small UX decisions (clear tabs, labels, visual trends) greatly improve usability

What's next for FinPrint by Fynx

Stronger forecasting (next-month spend and risk scoring) Smarter category-level budget caps and anomaly detection Better recurring-expense intelligence and subscription optimization Goal journeys (wedding, travel, debt payoff) with milestone tracking
