Units & currency · iPhone & iPad
Type it the way you’d say it.
A natural-language unit and currency converter — hundreds of units, 160+ currencies, answers as you type.
Most converters make you pick a category, then a from-unit, then a to-unit, before you finally type a number. UnitSnap reads the line the way you already write it.

The problem with menu converters
You should not have to open Length, then Kilometers, then Miles just to convert a distance. Type 5 km or 350f or 4800 yen. UnitSnap is built for that line, not for a stack of pickers.
How UnitSnap reads a line
Type the quantity the way you would write it. Answers appear as you type — no category menus first. All of these work:
5 km— length, weight, volume, temperature, and more350f— temperature with no space needed1 1/2 cups— mixed fractions and common abbreviations4800 yenor40 usd in eur— money in the same box5'11"— feet and inches when a height shows up

Units people actually use
UnitSnap is a unit converter. Length, weight, volume, area, speed, temperature, pressure, energy, data, and fuel economy — with the pairs people actually use put first.
- Pin a default (for example grams ↔ ounces, or km ↔ miles) so the next line matches how you work
- One-tap reverse when you want the other direction
- When a phrase is ambiguous (“180 pounds”), it offers both meanings and remembers which you meant
Currency in the same box
Travel and shopping use the same input. Type 4800 yen and the rate’s age is said in plain words — live, or cached from yesterday. Last rates stay on the device when you have no signal. 160+ currencies from published ECB reference rates.
