Press the play button to preview the sounds, and make sure your volume is up and not connected to an audio device you can't hear. It may take a second to fetch as it's getting the sounds from online.
Fantastic!
Cool but

Thank you! There's a guide in the app of how to set the sounds with Apple's 'Garage Band' app. If you still need help setting the sounds, write to trektheme@gmail.com
