My Price Log
My Price Log helps you record prices of products at local stores and compare them. It works entirely offline:You enter a list of stores.You enter a list of products sold at those stores.You enter, update and confirm the prices of those products at those stores as you shop.The app shows you the unit price of a product at all the stores which sell it, allowing you to decide where to buy it.There’s nothing particularly fancy or clever here. It’s a very simple, specialised database with a user interface optimised for easy use when you’re standing in a supermarket aisle with a basket or trolley.The app tracks how old each price is, so you won’t be misled by out-of-date prices. Old prices are indicated by icons and a simplistic inflation adjustment is applied to try to keep them somewhat useful, although for best results you should update the prices yourself. You can view a price’s history if you want to see how it has changed over time.The app will make a recommendation as to whether a price is good, OK or bad if it has enough information. A list of unit prices is also shown so you can decide for yourself.Customer loyalty scheme discounts can be specified for each store and these will be used to adjust the unit price when making a comparison between stores.Unit conversions are handled automatically, both within and between measurement systems. Metric, imperial and US customary units are all supported.
