Sleep timer counting

Values

“By playback time”

The timer counts the book’s minutes. At 1.5× a half-hour timer ends after twenty minutes by the clock, at 0.75× after forty. This is the default.

“By the clock”

The timer counts real minutes: a half-hour timer ends after half an hour at any speed.

Common to both

• While paused, the countdown stands still: the timer runs only while the book is playing.
• Skips and chapter jumps do not affect the countdown of a timer set for a length of time. After a jump, a “To the end of the chapter” or “To the end of the file” timer moves to the end of the chapter or file the book is now playing.
• “To the end of the chapter” and “To the end of the file” always count playing time: the boundary is a place in the book, and by the clock the timer would overshoot it.
• “Fade out at the end” lasts real seconds with either counting.
• With “Sync across devices”, the value travels to your other devices.

Where the difference shows

• The timer button in the player shows the remaining time in the chosen units: by playback time at 1.5×, the numbers drop faster than the clock.
• The rectangular Lock Screen widget shows in how many minutes by the clock the timer will fire: with “By playback time”, the time left is recalculated for the speed. While the book is paused, the widget shows no timer, and the number does not update every minute.

Tip

Want to fall asleep in exactly half an hour, whatever the speed? Choose “By the clock”. Want to measure out half an hour of the book? Keep “By playback time”.
