"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?

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).
