Unit Choice is a price comparison app that helps you compare unit prices by simply entering the price and quantity of each item. Even when products have different sizes, amounts, or pack counts, you can quickly check the unit price, cheapest option, average, and median. β€œIs this really a good deal?” β€œShould I buy the larger size or the smaller one?” β€œIs this more expensive than what I bought before?” Unit Choice was made to reduce those small moments of doubt while shopping, so you can choose with confidence. You can save your entries in a list, review them later, and compare the same products again whenever you need. Recommended for anyone who wants to avoid missing price differences, quantity differences, or better deals in everyday shopping.
