Turistický Deník is an unofficial Android application designed for travelers seeking business cards associated with various locations. It offers features such as the ability to find the nearest places, search for business cards by text or proximity to an address, and display a list of locations where business cards can be purchased. The app also includes a map view, enhancing navigation and accessibility for users on the go.

Additionally, users can mark business cards they have already collected, providing a convenient way to keep track of their finds. Despite being maintained sporadically, Turistický Deník serves as a useful tool for those interested in collecting business cards while exploring new places.
