Four categories, zero clutter.
Unit Converter handles the four categories you actually convert between day-to-day: length, weight, temperature, and speed. Pick a category, pick two units, type a number, done. The result updates as you type and a tap on the swap chip flips the direction.
It runs fully offline — just arithmetic and Intl-formatted numbers. Bookmarkable too: the current category, units, and value are reflected in the URL, so you can pin ?category=length&from=km&to=mi on your running log and only touch the input.
