## What is Unit Price?

Which pack is actually cheaper? Type in the price and the size, and this unit price calculator answers in a second — cost per 100 g, per litre, or per item, with the true best deal crowned on screen.

Shelf labels print the unit price in tiny grey text, when they print it at all, and they never account for the coupon in your pocket or the sales tax at the register. This app does. You can line up as many as 5 options at once, mix ounces against grams and litres against fluid ounces, stack a percent-off coupon with a flat coupon and a tax rate on each one, and watch the winner change the moment the real checkout price does. It runs entirely offline, so a dead spot in aisle 7 changes nothing.

WHAT YOU GET
- Know in seconds which pack costs less per unit, not just less on the sticker
- See exactly how much you overpay by choosing the wrong size, in money and in percent
- Compare products sold in different units without converting anything yourself
- Get a winner that already includes tax, coupons, member prices and multi-pack counts
- Keep your regular comparisons — olive oil, coffee, detergent — ready for the next trip
- Understand the math with short plain-English guides and a unit conversion table

PERFECT FOR
- Weekly grocery shoppers deciding between two sizes on the same shelf
- Warehouse and bulk buyers checking whether the giant pack really wins
- Households running a tight budget who want every trip to count
- Anyone tired of squinting at shelf tags and doing division in their head

WHY NOT JUST USE THE CALCULATOR APP?
Because a plain calculator gives you a number with no meaning. It cannot convert 1.5 lb into grams for you, it will not apply a 20% coupon and then 7.25% tax in the right order, it will not remember what you compared last week, and it certainly will not tell you which of five options wins. This app keeps all five side by side, in your currency, with the cheapest highlighted.

PRIVACY
Every calculation runs on your device. No account, no sign-up, no ads, no tracking, no analytics on what you buy. Your saved comparisons stay on your phone.

FULL ACCESS
Premium unlocks comparing 3 to 5 options at once, the Tax & Coupons tools, and your full saved comparison history. Available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. On the free plan you can compare 2 options and keep 1 saved comparison.

Next time you are standing in front of two sizes of the same thing, open the app, type in both, and buy the one that actually costs less.
