Sleep timer in mobile application

[foglar]

I want to listen to music before sleep. Currently I cannot find any way to turn music off after a certain period of time like in the Spotube (very similar music application, using Spotify to synchronize). I would like to pick after what time music should stop (10 min, 15 min, 30 min) playing. I cannot find any other way of setting this in the application.

@foglar just give a long press on album art img in player screen you will see option for sleep timer.
