Retron : Radio•Stream

Retron plays the songs saved on your phone. Playlists, favorites, lyrics, and chord charts stay in the app with the music. There is no account and no subscription. Open the app and the last song is waiting, paused, until you press play. Playback continues with the screen locked. The lock screen shows the title, artist, and artwork. Search by title, artist, album, or a line of the lyric. Browse artists, albums, bands, and churches. Sort by title, artist, recently added, most played, or last played. Favorites and playlists keep a set in order. A playlist can carry a service date, and each song can keep its key, tempo, and song number. Now Playing shows the artwork and the progress, with shuffle, repeat, and playback speed. Lyrics follow the song when the file has them. A chord chart opens beside the player. An equalizer, a sleep timer, and a short fade between songs are there when you want them. Bring songs in by importing audio files, including mp3, m4a, aac, wav, and flac. On the same Wi-Fi, the phone can also copy songs from a Mac running Retron. A song plays only after that copy has finished.
