Your music library should feel like yours. Flex Music is an independent music player and playlist manager for personal Plex Media Server libraries. Sign in with Plex, choose your server and enjoy your music at home, remotely or offline. BROWSE AND PLAY Explore artists, albums, tracks, playlists, genres and moods. Search inside large playlists, rate tracks back to Plex, and keep browsing while the mini-player plays. Expand Now Playing for artwork, synced lyrics when available, visualizers and the waveform progress bar. YOUR QUEUE, YOUR WAY Use Play Next to put a track first, or Play After Next to add it after your manually queued tracks. Assign these actions to your playlist swipes. Manage Up Next and Previously Played, reorder playlists, add whole albums and clone playlists. OFFLINE AND DATA SAVER Download your music with no paid track limit. Choose storage limits and keep favourites offline. Data saver asks your Plex server to convert audio to your chosen bitrate, with separate Wi-Fi and cellular preferences and measured transferred-data totals. Conversion depends on your server; data saved is compared with the original media size. MADE FOR YOUR SCREEN Choose themes, artwork effects and visualizers. Larger displays have room for the player and queue side by side. iPhone Duo adapts from a compact cover-screen player to a stacked portrait layout and a side-by-side player and queue when opened in landscape. Controls stay clear of the system strip, and your player and queue are retained as the layout changes. Music casting is free on supported receivers. Lyric casting brings available lyrics to Google Cast displays with Flex Music Pro. FLEX MUSIC PRO Free: browsing, playback, Smart Search, ratings, on-device lyrics, music casting, themes and visualizers, offline downloads, the Pinned Playlist widget, and editing playlists up to 100 tracks.

The Apple Watch companion is also included with Pro. CarPlay and Siri playlist playback are free. Monthly, yearly and lifetime plans unlock the same Pro features. Purchases are processed by the App Store and can be restored from Settings. Lifetime is a one-time purchase; subscriptions renew until cancelled in your store account settings.
