Справочник грибника is an encyclopedia of mushrooms that provides descriptions, images, and instructions for collecting and using edible mushrooms. The app also contains useful information on inedible and poisonous mushrooms. One of the most significant features of this app is that it works offline and does not require an internet connection to function. The database is loaded upon the first launch, so users are advised to use a Wi-Fi connection.

The app has a history feature that saves every article you have viewed, and a favorite feature that allows you to add articles to a list of favorites by clicking the "star" icon. Users can also edit or clear their history and favorites lists. Additionally, the app offers various settings, such as changing the font and selecting one of the color themes. Finally, the app has a "Random Article of the Day" widget. To see the widget in the list, the app must be installed in the phone's memory (the database can be installed anywhere).

It is important to note that this app contains ads.
