"Гусьгусь" is a free educational audio app for children created by Arzamas.academy. The app offers a wide range of topics such as history, astronomy, music, art, dinosaurs, memes, Vikings, and design. It also includes fairy tales, stories, and lullabies for the little ones.

The app can be listened to on the way to school, before bedtime, during a walk with the dog, or on a plane. It can be enjoyed by the whole family or just by kids. "Гусьгусь" is free, and there is always something to listen to. However, users can opt for a paid subscription to gain access to all courses, podcasts, and materials.

The subscription provides the following benefits:

• Access to all courses, podcasts, and materials
• Ability to add tracks, courses, or podcasts to "Favorites" for quick access
• Support for the developers, which will help them create even more great content for children.

New users are offered a two-week free trial period to access all the materials on "Гусьгусь."
