Real-Time Currency Conversion with Concurr

,

Hey, Avi here from Xetarev. Concurr is live. Built, polished, and primed for your browser. It’s your sleek, no-fuss currency converter that skips the clutter and gets straight to the numbers. I built it to be dead simple, super fast, and actually useful—whether you’re planning a trip, comparing prices, or just nerding out over forex data.

Try Concurr Now

From the moment you load it up, Concurr pulls in real-time exchange rates across 37 major world currencies. It’s all powered by the ExchangeRate-API, running behind the scenes with a single efficient call—so you’re not sitting around waiting. The interface? Clean. Responsive. Modern. Just pick your currencies, punch in a number, and you’re instantly converted. Want to flip the pair? One click. Want the latest rate? It’s already there. Want to know when it was last updated? Right there under the number. Every conversion happens client-side—no delays, no bouncing back and forth between the API and UI. Just fast, accurate data, streamed straight to your fingertips.

Here’s what Concurr brings to the table:

  • Real-time conversion between any supported currencies
  • Swap toggle to reverse your conversion with a click
  • Accurate to 6 decimal places, so you’re not guessing
  • 24-hour percentage changes to simulate market vibes
  • Persistent dark/light mode with localStorage memory
  • Responsive design for mobile, desktop, and everything in between

You’ll also see a clean breakdown of what’s happening under the hood—current rate, conversion math, and when the rates were last refreshed. It updates silently in the background every 24 hours. No fluff. Just facts. And if something goes sideways—bad input, flaky internet, or API hiccups—Concurr knows how to handle it. You’ll get meaningful feedback, not blank screens or cryptic errors. It validates your input, manages the state, and keeps the whole thing smooth.

Built entirely with vanilla JavaScript, Concurr doesn’t rely on bloated frameworks. Just ~200 lines of clean, class-based code doing one job really well. No libraries. No trackers. Just your currency math, straight up.
