Радио ULTRA онлайн is an unofficial music app developed by Maxim Troschinsky. The app provides a range of features for music enthusiasts who want to stay up-to-date with the latest rock news and listen to their favorite tracks. The app offers a variety of functions such as viewing information on the band from Wikipedia, searching for tracks online, watching music videos on YouTube, and sharing them on social media or messaging apps. Moreover, the app also includes a sleep timer that can add 5 minutes to the timer by tapping on the stopwatch icon. Additionally, the app has a notification bar control feature and allows users to add their favorite compositions to their favorites.

However, it is recommended to try the new Radio Point Online app instead of Радио ULTRA онлайн. The Radio Point Online app provides a more comprehensive and better experience for music lovers. It has a wider range of features and a more user-friendly interface. The app is also regularly updated with new features and bug fixes, ensuring a smooth and enjoyable experience for the users. Overall, Радио ULTRA онлайн is a decent app for music lovers, but it is highly recommended to switch to Radio Point Online for a better experience.
