The cheapest shelf price is not always the best deal

A larger pack can cost more per unit. A multipack can look like a bargain without actually being one. This app turns different pack sizes into a comparison that is easier to understand.

Three simple ways to compare

Choose the type that matches what is written on the pack.

Liquids

Bottles, cans and containers

Compare drinks, beer, wine, shampoo, cooking oil, toiletries and other products sold by volume.

Weight

Packs with different weights

Compare cereal, pasta, rice, coffee, produce, meat, pet food and other products sold by weight.

Items

Different pack quantities

Compare nappies, toilet rolls, tins, cans, razor blades, boxes and other count-based products.

Fast manual entry

Built for the shop aisle

The app deliberately keeps entry quick and predictable. Use presets where they fit, or roll individual digits for prices and quantities.

  • Optionally name a product so you can recognise it later.
  • Choose useful presets such as 330 ml, 440 ml, 500 ml or 568 ml.
  • Enter pack quantity without reaching for a normal calculator.
  • Save and move straight on to the next product.

Compare everything on the same basis

Switch between useful comparison amounts without re-entering your products. The app recalculates each option and highlights the best value.

  • Liquids can be compared by values such as 500 ml, a UK pint or a litre.
  • Weight comparisons can use values such as 100 g, 500 g or 1 kg.
  • Items can be compared by a useful count such as 1, 10, 20 or 50.
  • Change the product type to update the useful comparison choices.

Compare the cost of buying the same amount

Unit price is useful, but sometimes the real question is: what would the same amount cost if I chose the other pack?

Useful in the moment

A four-pack may cost more up front but still be better value. The same-amount comparison helps make that difference easier to relate to what you are about to buy.

Your shopping comparisons stay yours
