A unit converter that covers the things other converters leave out — and the currencies, cryptocurrencies and precious metals you actually check.
Download on the App StoreLive exchange rates for 160 world currencies, 126 cryptocurrencies, and gold, silver, platinum and palladium — converted the same way as any other unit.
Type a unit name and get matches from every section, each tagged with the category it belongs to, so the same name in two places is never ambiguous.
Choose significant figures to keep small numbers detailed, or a fixed number of decimal places to line every result up in the same column.
Rearrange the categories you use, hide the ones you don't, and launch straight into a single converter, skipping the home screen entirely.
Fully localized in 13 languages, including right-to-left layout for Arabic, with numbers formatted to your region's conventions — a comma decimal separator where that's what people write.
…and 56 more.
Questions, bug reports and requests for units or categories are all welcome — the unit list has grown mostly from people asking.
Email strikespark.feedback@gmail.com. It helps to include your device, your iOS version, and the language the app is running in. If it's a conversion that looks wrong, the two units and the number you typed are usually enough to reproduce it.
You can also reach this from inside the app: Settings → Give Feedback, which fills in your app version, iOS version and device model for you.
