No subscription (iPhone/iPad app by Joseph Chen.) - Source: https://appshunter.io/ios/app/unitsnap-unit-and-currency/id6797423240 (this page in markdown: same URL + `.md`) - Developer: [Joseph Chen](https://appshunter.io/developer/6791370163) - Category: Utilities, Reference - Price: $2.99 - Age rating: 4+ - Requires: iOS 17.0 · 3 MB - Languages: American English - Released: 2026-09-24 - Data updated: 2026-10-21 ## What is UnitSnap? Type it the way you would say it. "5 km". "350f". "1 1/2 cups". "4800 yen". UnitSnap reads the line the way you actually write it and answers as you type — no picking a category first, no choosing two units from two menus before you see a number. WHAT IT CONVERTS • Length, weight, volume, area, speed, temperature, pressure, energy, data and fuel economy — hundreds of units • 160+ currencies, from the European Central Bank's published reference rates • Cooking measures, fractions included: 1 1/2 cups, 3/4 tsp • Feet and inches the way people actually write them: 5'11" MONEY, HONESTLY DATED Currency answers say how old the rate is in words — "Live rate, fetched a moment ago", or "Cached rate from yesterday, not today's" — so you never have to work it out yourself. The last rates stay on the device, so it still answers with no signal. BUILT TO TAKE STEPS OUT • The box is already focused when the app opens — just start typing • The keyboard opens on numbers, because every conversion begins with one • "180 pounds" asks whether you mean weight or British pounds, then remembers your answer • Tap any unit to make it the default for that measure. It sticks • One tap reverses any conversion • Pin the ones you reach for constantly ALSO INCLUDED BMI in US or metric units, and unit conversions for a set of common health values — glucose, creatinine, cholesterol, calcium and others — along with body surface area and ideal body weight. UnitSnap is a unit converter, not a medical device and not a clinical decision tool. It does not recommend a dose, a diagnosis or a course of treatment, and is not intended for use in patient care. PRIVACY UnitSnap collects nothing. No analytics, no advertising, no tracking, no account, no sign-in. Your pins, preferences and history stay on your device. The only request it ever makes over the network is for published exchange-rate reference data, and it sends nothing about you when it makes it. One purchase. No subscription, no ads, nothing else to buy. ## Is UnitSnap safe? Not enough ratings yet to assess UnitSnap. ## Is UnitSnap legit? UnitSnap: Unit & Currency has limited verification signals.

Small fixes. ### 1.0.2 — 2026-10-11 Same conversions. The App Store page now leads with currency and cooking measures, which is what the app already does. ### 1.0.1 — 2026-09-26 UnitSnap can now ask whether you would like to rate it — at most once in a while, and only after it has actually answered something for you. Every unit name now reads in US spelling: meters, liters, milliliters. British spellings still work when you type them, so "2 litres" is understood exactly as before. ### 1.0 — 2026-09-24 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
