The smartphone app could also already stream in lossless quality to Chromecast devices – but not directly on the handheld. Now the "HiFi" version can also be played on iOS and Android smartphones from the Deezer app or in the browser. Songs can even be downloaded and listened to on the go without an Internet connection. Lossless streaming "to go" would consume huge amounts of data. Deezer has expanded its catalog of hi-fi quality titles by 11 million titles to 52 million titles. Deezer reports that the number of hi-fi subscribers increased by 45% last year. So there seems to be a trend towards better sound quality.
