Built for real trips

The numbers you need, without extra ceremony

Currency Lens keeps live reference rates, personal exchange rates, and camera conversion in one consistent workflow.

01

Multi-currency rates

Enter an amount once and compare selected countries and currencies together. Pull down to request the newest available data.

02

Exchange log

Record what you paid, what you received, the exchange date, and a note. The calculated personal rate can be reused for price conversion.

03

AR price conversion

Point the camera at a displayed price and convert it using either the latest available rate or a manual rate from your exchange log.

04

Remembered choices

Your selected currencies, recent amounts, manual rate, and language are saved locally so the app is ready when you return.

Common questions

Before you travel

Are rates guaranteed to match my bank or exchange counter?

No. Rates are reference information and may be delayed or differ from banks, card issuers, payment networks, or exchange providers. Confirm the final amount with the provider completing the transaction.

What happens without a network connection?

The app shows the last successfully cached rates and marks them as offline data. A network connection is required only to request newer rates.

Does the camera upload what it sees?

No. Camera frames, recognized text, and converted prices are processed on the device and are not uploaded to the developer.

Does AR price conversion require a purchase?

Yes. AR price conversion uses a one-time, non-consumable purchase. Rates and exchange logs remain free, and there is no subscription.
