Bottom Keeper в Android Market

Bottom Keeper (v. 1.02) Разработано gpsoft

A notepad for keeping price information. It memorizes price information of various items and shows you the bottom price of each. It's been mainly designed for use in Japan, for example it uses 'yen' for the currency unit and some of preset records are written in Japanese. Though that may be a bother to non-japanese users, I believe it's not a crucial matter.
