Listen to lessons
Every lesson has audio, and it keeps playing when your screen locks.
Updated October 2, 2026
Every lesson has an audio version next to the video. Listen in the car, on a walk, or on a job site.
- Keeps playing when the screen locks. Use the controls on your lock screen to pause or play.
- "Audio loading". On a weak connection the button says this while the audio starts. Give it a moment.
No sound? See Audio isn't playing.
