# Finnik Finance Tracker

**FinTech · iOS & Web · AI-Powered Development**

"The way to your financial freedom" — A focused finance tracker for multi-currency users who need clarity, not complexity.

## The Challenge

Like many professionals managing finances across multiple currencies, I struggled with currency chaos, subscription creep, and not knowing what my balance would be next month when bills hit.

I needed a focused tool answering three questions:

- Where is my money right now?
- Where is my money going?
- Where will my money be?

## Research & Competitive Analysis

Gap in market for focused, multi-currency account tracking. Competitors like ClickUp, Monefy, GoodBudget, and Spendee were either too simple, too complex, or lacked multi-currency support.

## AI-Powered Development

Built with Claude AI (strategy & documentation), Trae AI (web platform), and Cursor AI (native iOS with SwiftUI).

| Approach | Hours |
| --- | --- |
| Traditional development | ~350 hours |
| AI-assisted development | ~100 hours (71% savings) |

## Web Platform Features

- Multi-account dashboard across USD, EUR, UAH
- Time-based balance projections
- Subscription tracking with monthly totals
- Real-time currency rates from National Bank API

## iOS Native App

SwiftUI implementation with native navigation, CoreData offline caching, haptic feedback, and Apple HIG compliance.

## Results

| Metric | Outcome |
| --- | --- |
| $0 | Dev spend (excluding AI subscriptions) |
| $120/mo | Saved by canceling unnecessary subscriptions |
| 2 weeks | Time invested including learning new tools |

## Key Learnings

- AI excels at implementation; humans excel at strategy
- Quality documentation is AI's superpower enabler
- Simple is harder than complex—it requires discipline
