Units are ranked by frequency, so your most-used units appear at the top, and programmable blue buttons let you save favorite conversions for instant recall. All features are accessible on the main screen, eliminating tedious switching between screens.

The app supports a swap key for quick unit swaps, and settings are saved automatically when you leave. Currency rates update live when online. If you have problems, contact support at support@fappsworld.com.

## Review summary

Users praise Unit Conversion for being easy to use, reliable, and covering a broad range of units, making it a go-to tool in daily life and professional contexts (nursing, piloting, cooking).
