The 4 Best Currency Exchange Apps in 2026
The exchange rate you see on Google is not the one you will be charged: between the interbank rate and what you actually pay there are fees, margins and, if you accept the conversion offered by the card terminal abroad, a surcharge that can reach five percent. In this guide we compare the 4 best currency exchange apps in 2026.
Apps to check and exchange currencies while travelling

Pros

Frequently asked questions
Why doesn't the rate I'm charged match the one in the app?
Because XE and the converters show the interbank rate, the one banks use between themselves and that a private individual cannot access. On top of that rate, your bank or the exchange bureau adds a margin. Wise and Revolut come quite close to the interbank rate and charge the fee separately, which makes the cost transparent.
Should I accept the exchange rate offered by the card terminal abroad?
No. When a card terminal or a cash machine asks whether you want to pay in euros instead of the local currency, that is called dynamic currency conversion and it always works out worse: the merchant applies its own rate with a margin that is usually between three and five percent. Always choose the local currency and let your bank do the conversion.
Do they work offline?
Yes, and that matters when you land in a country with no data. XE and Conversor de Divisas store the last rates they downloaded and keep converting without internet. The figure will be slightly out of date, which is irrelevant for working out whether a twenty-thousand menu in the local currency is expensive or cheap.
Is it better to carry cash or pay by card?
With a card that charges no exchange fee, such as those from Wise or Revolut, paying by card usually beats changing cash at an exchange bureau, where margins are high. It is worth carrying some local cash for places that don't take cards, and withdrawing it from a bank cash machine at your destination rather than changing money at the airport, which is the most expensive option.
