How do I uninstall my SoundCloud mobile app?

Good question. 

To uninstall the SoundCloud iPhone or iPad app:
Hold down one of your iPhone app's icons, until all the icons start to shake.  Then click on the "X" above the SoundCloud app's icon and select "delete"

To uninstall the SoundCloud Android app:
Go into your phone's application settings, find the SoundCloud, tap it, and then tap "uninstall"
