Currency converter that works offline

5 currencies are free forever. The core converter and offline mode work without paying — pick the 5 you use most. Moneta Plus is the optional upgrade for the full 180+ catalog, 5-minute refresh, and the camera price scanner. No ads, no data brokers, no account required.

Moneta shows the live mid-market exchange rate — the midpoint between bid and ask prices on the interbank market, where banks settle with each other. Your bank or card processor adds 1–4% margin plus fixed fees, so the rate they give you is always worse than the mid-market figure. With Moneta you see the clean exchange rate first, so you can spot the markup when you spend or transfer abroad.

Rates come from proprietary sources: directly from central banks and major FX trading platforms. The app refreshes every 5 minutes while online. Each fresh set is cached locally so the calculator works in offline mode (airplane, tunnel, abroad with no roaming). When your phone reconnects, Moneta pulls the latest set in the background. Accuracy is within a fraction of a percent for major currency pairs.

Yes. Rates are cached on your device, so the calculator works in airplane mode, in tunnels, or off-grid. The last-sync timestamp is always visible. When your phone reconnects, Moneta pulls the latest rates in the background.

Moneta supports 180+ currencies including the US Dollar, Euro, British Pound, Japanese Yen, Swiss Franc, Yuan, Canadian Dollar, Australian Dollar, and most other ISO 4217 fiat currencies. Plus major cryptocurrencies (Bitcoin, Ethereum, Solana, and 40 others) and precious metals (gold, silver, platinum, palladium).

Yes. Moneta is a multi-currency converter covering every major pair — USD to EUR, EUR to GBP, GBP to JPY, USD to MXN, EUR to TRY, USD to INR, and any combination of 180+ world currencies. You can also convert between fiat and cryptocurrency (Bitcoin, Ethereum, Solana, and 40+ others) or precious metals (gold, silver, platinum, palladium). Set your home currency once and any conversion is one tap away.

Three things. (1) It works offline, so the converter keeps functioning on a plane, in a tunnel, or in a country before you have bought a local SIM. (2) The Price Lens scanner reads price tags, menus, and receipts through your camera and converts to your home currency without typing. (3) No ads or pop-ups when you are stressed, jet-lagged, and trying to figure out whether 2,400 Thai baht is reasonable for dinner.

Yes. Moneta Plus unlocks historical exchange-rate charts for any currency pair from 1 day to 10 years. Useful for spotting trends in USD/EUR, watching Bitcoin against the US Dollar over a market cycle, or checking what a rate looked like on a specific date for an expense reconciliation. Charts cover fiat currencies, cryptocurrencies, and the four precious metals (gold, silver, platinum, palladium).
