Hi, if you still need it : I use Deezloader Remix, it's the best in my opinion ( You can download songs you put in your Deezer playlists instead of searching for them one by one for exemple ) It's available on Windows and Android, I don't know about iOS.
If anyone is curious about working options for android devices and windows atm, its AIDS (yes, that's the actual name of the application I promise) and Freezer
