CertusFX Currency Converter FX

CertusFX turns currency data into decisions. Convert with confidence, track the pairs you care about, and see what the numbers actually say — built for people who need FX to be precise, not flashy. WHAT'S INSIDE Currency converter A real calculator built into the converter — type expressions, not just numbers. Exact decimal math, no rounding drift. Daily European Central Bank reference rates across 30 currencies, with full breadth for Pro via ExchangeRate-API — and the reference date always shown on screen. Markets Search any major pair, add it to your watchlist, compare one currency against another, and follow 30-day charts on the pairs that matter to you. Yield curves Government bond yields from official sources, charted and comparable across countries. The rate differential that drives currency moves — visible instead of implied. Trends and AI Outlook (Pro) A directional signal for every major-currency pair — plus every other supported currency against the US dollar and the euro — computed from 30-day price momentum, with 10-year yield spreads added where both currencies have them, then explained in plain language grounded only in those numbers. No hype, no invented narratives. Offline-ready Last-known rates stay available with an honest timestamp when you lose signal. HONEST BY DESIGN Rates are reference rates — daily European Central Bank rates for the core set, ExchangeRate-API for full Pro breadth — not a real-time trading feed, and CertusFX says so, everywhere. Every figure carries its date. Nothing claims to be fresher than it is. PRO ACCESS One month and one year passes. No auto-renewal and no subscription trap — a pass runs out, and that's it. Pro unlocks full currency breadth and the AI Outlook. CertusFX is an information tool, not financial advice. Always do your own research before acting on any rate or outlook.
