Radio Boy is a free lifestyle app developed by Mo Flux LTD exclusively for iPhone users. This app allows you to listen to 5 stations including FM4, BBC6, STUBRU, WEBFUNK, and DUBLAB. Additionally, users have the option to add custom stations by searching for them by name.

One standout feature of Radio Boy is the smooth channel switching capability, offering crossfade audio transitions between stations (excluding iOS12 devices connected to AirPlay). Users can view the currently playing track within the app and on the Lock Screen, and have the convenience of opening the current track in Spotify or the Music App to add it to their playlists. Furthermore, the app supports background play, allows for easy channel navigation through swiping or double-clicking the earpod remote control button, and is compatible with iOS 9.3 or later devices for broad accessibility. Radio Boy boasts a small app size, ensuring quick app start-up, and is completely free with no ads.
