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!
the time machine idea is honestly pretty clever, spun back a few months to check euro rates and it worked smoothly without any signups getting in the way
The spinable wheel as a way to scrub through historical rates is such a clever way to make boring financial data feel actually fun. And shipping it ad-free with no signup is a rare treat these days.
Spun the wheel back to early 2021 and it was cool to actually see how the euro hit its strongest stretch against the dollar, no signups or clutter in the way. Clean little tool.
Spun the wheel back a few years to check rates from a trip to Japan and it actually matched what my bank charged me, which never happens with these tools. The whole thing loads instantly and the time machine idea is genuinely clever.
Spinning back through past EUR rates felt weirdly satisfying, way more fun than another plain converter page. Love that it just works without any sign-up hassle.
