Step 1: To set the sleep timer, tap the ‘Sleep’ icon from any audio’s player screen.
Step 2: Then select how long you would like the audio to play before it stops. Or, you can choose the “end of track” option if you’d like the audio to stop at the end of a chapter or track. You can also choose ‘Custom’ if the length you would like is not displayed as an option.
You’ll know the timer has been set successfully when you see the sleep icon shaded in pink and the amount of time left on your timer shows at the top of the audio image.
If you no longer want the sleep timer to be active, you can turn it off by tapping on the Sleep icon again and then choosing ‘Off’.
