NumoDo the math in the amount
Add up a bill, split it, or add shipping before you convert. The keypad works like the calculator you already know, and every currency follows as you type — up to five at once.
For travelers
Know the price before you tap your card.
Numo turns any price abroad into your currency in a second — point the camera at a tag or a menu, at dinner or in airplane mode.
Free · No ads · For iPhone
Picture this. Then tap.
At the market
Point the camera at the tag and see the price in your own currency before you haggle.
Splitting dinner
Add up the bill and divide it right in the amount field: 86 + 12 ÷ 4.
No roaming
Rates are saved on your iPhone, so it works with data off or in airplane mode.
Built on trust. Not on tracking.
No account to create, no ads to sit through, and rates from sources you can name.

Questions, answered.
Does it work without internet?
Yes. The latest rates are saved on your iPhone and used offline. The app shows how fresh they are and refreshes them when you’re back online.
Can I convert a price by pointing the camera at it?
Yes. Tap the camera key on the keypad and point it at a price tag, a menu or a receipt; Numo converts the price it reads. You can also scan a photo. Text is recognized on your iPhone and images are never uploaded.
Can I keep different currencies for different trips?
Yes. In Settings › Currency setups, add a list such as Travel or Work with its own currencies and icon, then swipe the title on the main screen to switch between it and your default list. Currency setups are part of Numo Pro.
Why is my card’s rate different?
Banks, cards, ATMs and exchange offices rarely use the reference rate. With Numo Pro, add your bank’s fee — a percentage, a fixed amount or both — and every conversion shows an estimate with a cost breakdown, with the reference rate in view. Save fees like Card +2% or ATM +3% and switch in one tap. Your bank’s final charge may differ.
Is Numo free?
Yes. The full converter — every currency and 20 cryptocurrencies, the calculator, the price scanner and offline rates — is free with no ads, along with one price alert, 30 days of rate history and one custom rate and currency. Numo Pro is an optional upgrade for currency setups, bank fees, up to 20 alerts, a year of rate history, advanced widgets, sharing from other apps and app icons — monthly, yearly or as a one-time purchase.
Which widgets are there?
The Small rates widget is free and also shows in StandBy. Numo Pro adds larger and Lock Screen widgets, Smart amounts and Rate trend, a widget base currency of your choice and a Favorite Currency control in Control Center.
Any price, in your currency.
