## What is 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.

## Version history (last 5 releases)

### 1.0.4 — 2026-10-04

Buying a pass is now more dependable. If your payment takes a while to clear, Pro turns on by itself as soon as it does. Right after you buy, Pro stays on while the store confirms your purchase. A pass you bought before signing in now moves to your account when you sign in. Plus stability improvements that help us fix problems faster.

### 1.0.3 — 2026-09-27

Reliability update. CertusFX now sends us crash reports and basic usage statistics, so we can find and fix problems faster — often before you run into them. They never include your name, email or account details.

### 1.0.2 — 2026-09-24

Sharper on tablets and in Spanish.
1. Converter results now show in full on tablets and iPad.
2. Amounts reformat instantly when you switch language.
3. Shorter, clearer alert labels in Spanish.

### 1.0.1 — 2026-09-15

Rate alerts now check in the background — get notified even when CertusFX is closed.
Free alerts cover the 30 major currencies.
Fixed two alert bugs: alerts no longer re-fire, and never trigger on stale rates.
Pro users can now extend a pass before it expires — time stacks onto your existing expiry.

### 1.0 — 2026-09-03

No release notes.
