Like4Like is an Android App that lets you compare the prices of 2 products. Often products are sold in different quantities, or even different units (e.g. grams and Ounces). Comparing prices when the quantities are different can be very difficult. Like4Like will make the comparison and tell you which is the cheaper product (even if they are in different units) and by how much (as a percentage).
For example:-
A 500 mL bottle of vinegar costing $1.50 is 5.96% cheaper than a 25 Fl Oz bottle of vinegar costing $2.35
What the buttons do.
Clear - removes all entries from the Quantity and Price fields.
Unit - Changes the measurement units from Solids to Liquids or vice-versa.
Compare - Compares the entries and shows which is the cheaper product
US/UK - Toggles between US measures and UK measures
Notes- Like4Like is intended as a simple shopping aid, for quick and easy comparisons; it is not a scientific calculator.
Like4Like assumes that both products are the same currency, therefore there is no need to enter a currency symbol.
Additional measures may be introduced with future versions of Like4Like.
