Voice Recorder is an app for recording lectures, conversations, and other sounds (previously called Sound Recorder). Hit the big Record button (1), and add markers (3) to identify key moments as you record or play (2). Then you can trim (5), rename (7), or share your recordings (4), which are saved in Documents > Sound recordings. Select the trash can icon (6) to delete your recording, or the three dots (8) for more options.
