UnitSwap — Unit & Currency Converter, Instantly

The fast, clean, offline-first converter for everyday life: length, weight, volume, temperature, area, speed, and time — plus live currency exchange rates — all in one app, with results that update as you type. No "Convert" button. No loading spinner. No clutter.

CONVERT ANYTHING, INSTANTLY — 100% OFFLINE
Length, weight, volume, temperature, area, speed, and time. Every one of these conversions runs entirely on your device — no network access required, ever.

LIVE CURRENCY EXCHANGE RATES
Convert between major world currencies using rates that sync quietly in the background. Rates are cached on your device, so conversions are instant and still work offline using your last known rates — never an error, never a blank screen.
