Boudy, chaty, bivaky, studánky is a free Android application designed for travelers and adventurers who love to spend their time in nature. The app helps users to find shelters, cabins, bivouacs, and wells, which are available for public use in the Czech Republic. The app provides the location, description, and photos of the shelters, as well as information about their capacity, facilities, and availability.

The app offers a user-friendly interface and a simple search function that enables users to find the nearest shelter relevant to their needs. The app also provides a map view that shows the location of all the shelters in the Czech Republic. The app is available in the Czech language only.

However, the app has been discontinued and replaced by a new and improved version called "Nature application." The new app offers more features and a better user experience. Therefore, it is recommended to download the new app from the Google Play store.
