Type it the way you'd say it.
Most converters make you pick a category, then a unit, then another unit, before they show you a number. UnitSnap reads the line the way you actually write it — and answers as you type.
No menus. No categories. Just the line.
Every input UnitSnap accepts begins with a number or a currency symbol — so the keyboard opens on digits, and the box already has focus when the app opens. Two taps removed before you've done anything.
Hundreds of units
Length, weight, volume, area, speed, temperature, pressure, energy, data and fuel economy — with the pairs people actually use put first.
Money, honestly dated
160+ currencies, and the rate's age said in words: “Live rate, fetched a moment ago”, or “Cached rate from yesterday, not today's.” Never just a date you have to do arithmetic on.
The way recipes are written
1 1/2 cups. 3/4 tsp. 5'11". 350f. If a person would write it that way, it parses.
It asks when it can't know
“180 pounds” could be weight or British pounds. UnitSnap offers both, guesses neither — then remembers which you meant so it never asks twice.
Reverse in one tap
Any answer flips and rebuilds the query from the result, targeted at the unit you started from.
Preferences that stick
400 g answers in ounces, which is right for a recipe and wrong for a parcel. Tap pounds once and grams answer in pounds from then on.
Lab values, both ways, without a browser tab.
Conventional and SI units for the analytes that actually come up on a shift, plus the two patient-specific figures worth having in the same place — computed from the numbers you enter, with the inputs kept on screen next to the answer.
Body surface area
Mosteller. 170 cm and 70 kg reads 1.82 m², with both inputs still visible.
Ideal body weight
Devine, by height and sex.
BMI, US or metric
Switching units changes how the same stored number is shown — it never quietly recomputes a slightly different BMI from rounded text.
UnitSnap converts units and derives values from the numbers you enter. It does not recommend a dose. Verify against your institution's protocol and, per your facility's policy, a second clinician.
It collects nothing. Not “anonymised” — nothing.
Your pins, preferences, remembered choices and history stay on the device. The only request UnitSnap ever makes is for published exchange-rate reference data, and it sends nothing about you when it makes it.
One purchase. That's the whole model.
Pay once. No subscription, no advertising, nothing else to buy, and no feature held back for a second purchase.
