Hey Product Hunt!
CurrencyWheel started as a personal frustration: as a musician paid in dollars who invoices in euros, I was constantly jumping between Google, exchange rate charts, and historical data just to do basic currency math.
So I built a small Windows widget first, just for myself. Then I got slightly carried away and turned it into a full web app with a Time Machine.
How it works:
1. Pick a currency pair
2. Enter an amount
3. Spin the wheel to travel back in time and see the historical rate
Completely free, no registration, no ads. All feedback welcome!
