What it does well

Made to get you to the number fast, then stay out of the way.

Focused by default

One app for units, FX, and crypto

Move between measurement conversion, live currency checks, and crypto comparisons without changing tools.

Made for real numbers

Adaptive formatting that stays readable

Large totals stay clean, tiny rates stay precise, and the app shifts decimal detail based on magnitude.

Useful even when coverage drops

Offline-friendly exchange data

Recent exchange rates are cached for up to an hour so your latest lookups remain available on the move.

Switch between units, fiat, and crypto in seconds, keep your most-used pairs close with favorites, and use the home screen widget for a fast daily snapshot without opening the app first.
