Гудок is a free iPhone app developed by Management Company T2 Rus OOO. This app allows you to replace regular phone call ringtones with musical hits or jokes. With a wide selection of fresh hits, genre classics, humor, and unique sounds, you can stand out and be creative with your phone's capabilities.

The app offers convenient navigation and search options within its catalog, making it easy to find the perfect melody or joke for your calls. All melodies available on Гудок are free to use and you can even create playlists with multiple tunes. However, to play these melodies instead of regular ringtones, you need to have the Tele2 "Гудок" service activated.
