Convert currency instantly
$0.99 · Designed for iPad. Not verified for macOS.
Convert money the moment you open the app — simple, no ads and smart
ChangeRate is a fast, offline-friendly currency converter built for travel. Type an amount into either currency and watch the other update instantly — tap the currency badge to change it, or tap the lower panel to convert in the other direction.
SMART BY DEFAULT • Detects your current currency from your location, and your home currency from your device's language and region • Never suggests converting a currency into itself — if home and away happen to match, it picks a sensible alternative automatically • Remembers your last currencies, or pin your own defaults in Settings
WORKS OFFLINE Exchange rates are cached the moment you're online, so ChangeRate keeps working on a plane, in the subway, or with no signal at all.
MADE FOR HOW YOU ACTUALLY USE IT • Star your own "Frequently used" currencies, or let ChangeRate learn from what you actually pick • Full landscape layout — the keypad sits beside the display instead of squeezing underneath it • Choose a decimal precision from whole numbers to three decimal places, right from the keypad • Four typefaces to choose from, including a monospaced option for reading numbers at a glance • Every currency shown with its flag and official name — 166 currencies covered
PRIVATE BY DESIGN Location is used only to guess your starting currency, handled through Apple's own system services. ChangeRate has no servers of its own, no accounts, and no analytics — there's simply nowhere for your data to go.
