Yes you can! To add a bookmark at any time while playing your audiobook, simply tap the "Bookmark" icon located at the upper right corner of the audio player screen.
Note that you can add as many bookmarks as you like‚ whether the audiobook is playing or paused. To access saved bookmark(s) navigate to the "Tracks" screen by tapping the menu icon at the upper left corner of the audio player screen (it looks like 3 stacked white lines). Once on the Tracks screen, tap "Bookmarks" at the top of the screen and then tap any bookmark in the list to resume playback from that point. Also note that your bookmarks are saved globally and can be accessed on all of your Android and iOS devices.
