In addition to the alarm sounds that come pre-loaded on the Restore, a membership to Hatch+ will offer additional content that you can use to start your day! You can view these options when setting up or editing a sunrise alarm - you swipe right to "see more" options.
Those with Hatch+ will be able to play any piece of content shown, while those without Hatch+ will still be able to freely choose from the sounds found under "alarms"
