Play-Fi is a free app that provides whole-home wireless audio systems for smartphones and tablets. It is powered by DTS Play-Fi technology, which offers a breakthrough listening experience over Wi-Fi. The app allows you to stream your favorite tunes over Wi-Fi right from the app to speakers from DTS Play-Fi product partners.

The audio quality and reliability are outstanding and you can enjoy music from your phone in one room or all your rooms. The app offers built-in streaming options, including worldwide music services, AM/FM and Internet radio, and DLNA servers. You can also play your device's music library, including your iTunes playlists, as the app automatically organizes and indexes the music for you.

The app handles set-up for your speakers and gives you full control of volume and speaker selection. You can choose one, set up speaker groups, or stream to all of them at once. The app also manages speaker groups for Spotify Connect.

Please note that the Play-Fi app is companion software to audio products enabled with Play-Fi technology and is not intended as a stand-alone audio player.
