About this app

You only ever need a conversion in the middle of something else. The recipe is waiting, the drawing is open, the homework is half done — and a web search for "cups to ml" buries the answer under ads and recipe blogs. By the time you find it, you've lost the thread, and tomorrow you'll search the exact same thing again.

Unit Converter answers while you type. Open it, pick a category, and the result updates with every keystroke — no convert button, no page load, no scrolling past sponsored results. Your last 50 conversions stay one tap away, so the pairs you use every day (the same metric-imperial switch, the same oven temperature) replay instantly instead of being typed again.

KEY FEATURES
• Live conversion — the result updates as you type
• Swap — reverse from/to units in one tap
• Conversion history — your last 50 conversions, tap any to replay

• No account, no setup — open, convert, done
