Unit Choice

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. “Is this really a good deal?” “Should I buy the larger size or the smaller one?” “Is 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.

Verdict
The clearest difference is ads: Unit Choice at none against Store Watcher's shown. Unit Choice also leads on update cadence (every 4 days vs every 4 weeks). On price, in-app purchases, chart position and device support there is nothing between them.
