Unit Converter Metric Imperial

A unit converter that answers while you type. Pick a family, tap the keypad, read the result — no equals button, no menus to dig through, no ads in the way. Most converters hide their categories inside a dropdown. UnitFlip puts them on a swipe: slide sideways to move from length to mass to temperature, tap the arrows to flip the pair when you chose the units backwards, and watch the number update live on a full-screen keypad built for thumbs. 54 units across 8 families, every calculation done on your iPhone. WHAT YOU GET - The result appears the moment you type — nothing to press, nothing to wait for - One tap flips the pair, so a wrong direction costs you a second instead of a restart - Eight families on a swipe: length, mass, temperature, area, volume, speed, time and data - Star the pairs you use every day and reopen them instantly from Favourites - Tap the result to copy it straight into a message, note or spreadsheet - Reference tables of real-world anchors, so a number turns into something you can picture PERFECT FOR - Home cooks converting cups, grams and Fahrenheit in the middle of a recipe - Travellers flipping between miles, kilometres and Celsius abroad - Students and DIY projects checking inches, metres, litres and square feet - Anyone tired of typing "kg to lbs" into a browser five times a week WHY NOT JUST SEARCH THE WEB? Because a search needs signal, a page load and an ad before it gives you a number. UnitFlip works on a plane, in a basement, and in a country where your data plan does not. Every conversion runs offline on your device, and nothing you type ever leaves it. PRIVACY No account, no sign-up, no tracking, no ads. Your saved pairs stay in the app on your iPhone. There is nothing to log in to and nothing to leak. FULL ACCESS Full access unlocks every unit family, the flip keypad, Favourites and the Reference tables. Three plans: weekly, yearly, or a one-time lifetime purchase. Weekly and yearly are auto-renewing subscriptions that renew unless cancelled at least 24 hours before the current period ends; you can manage or cancel them anytime in your Apple ID settings. Lifetime is a single payment with no renewal. Open the Convert tab, swipe to the family you need, and type one number — that is the whole app. Terms of Use (EULA): https://web-levi.web.app/terms Privacy Policy: https://web-levi.web.app/privacy-policy Questions?
