Крамниця is an Android application that allows you to exchange earned grains of sand for parts of the "Book of ROD" and information about significant figures and events from Ukrainian history. This app is the first step towards expanding the R.I.D. project into a system of applications. With Крамниця, you can explore familiar and unfamiliar corners of Ukrainian history and culture and discover the beauty of your native language.

With regular updates in each section, you can join the five characters of the "Book of ROD" on a journey through 2,500 years of Ukrainian history. The "Figures" section provides insight into the impact of individuals on the development of the entire state, while the "Events" section not only describes what happened in the country over the centuries but also provides documentary evidence, extracts from documents, and excerpts from chronicles and literature.

Overall, Крамниця is a fantastic educational tool for anyone interested in Ukrainian history and culture. It is free, easy to use, and regularly updated with new information.
