Which pack is cheaper? Quick price-per-unit compare. No ad on price compare math
UnitWise answers one question, fast: which one is actually cheaper per unit? Enter the price and size of two or more items, and see the winner instantly — no navigating between "enter" and "see result." WHY UNITWISE IS DIFFERENT Every top-ranked "unit price" and "calculator" app today is a general calculator with this feature buried inside it, or an abandoned utility that hasn't been updated in years. None of them is a dedicated tool for this one job — and their reviews show it: full-screen ads, paywalls on a basic calculator, and permissions a comparison tool has no reason to ask for. • ONE JOB, DONE WELL — compare price-per-unit for 2 or more items on one screen. That's the whole app. • NO FORCED ADS ON THE COMPARISON — a single small banner, never inside the input fields or the result itself. No full-screen interstitials. • NO ACCOUNT, NO LOGIN — open it and use it. • NO UNNECESSARY PERMISSIONS — no contacts, no storage-wide access, no location. It's a calculator. • WORKS FULLY OFFLINE — it's arithmetic. There's no reason it should need a network connection to compare two prices. • AUTOMATIC UNIT CONVERSION — mixed units within the same category convert automatically (liters ↔ milliliters ↔ gallons, or kilograms ↔ grams ↔ pounds), so you can compare a 2L bottle against a 64 fl oz jug directly. • HONEST ABOUT WHAT IT CAN'T KNOW — UnitWise never silently compares a volume-labeled item against a weight-labeled one (a real shelf problem — edible oil is a classic example). Converting between the two needs the product's density, which no app can know just from the label. UnitWise tells you that plainly instead of guessing at a number you can't trust. COMPARISON HISTORY Your recent comparisons are saved on your device, so re-checking a common purchase — "is the 2L or 4L bottle the better deal at my usual store" — is instant the next time. BUILT FROM REAL COMPLAINTS UnitWise was designed after reading thousands of reviews of the apps currently ranked for "unit price calculator." The dominant complaint, by a wide margin, was ads overwhelming a simple tool. UnitWise is built specifically not to repeat that.
