I made two apps and I want to delete one of them that I am not even going to upload, so can someone please help me? Thank you in advance.
Thanks for posting! Completely deleting an application entry from the Dashboard is not possible at this time. You can suppress live apps yourself, see:
In addition, if you haven't published the app yet, you can always re-use that application placeholder for a different app. Simply edit its description, title, screenshots, etc. and upload a new binary later. Thanks!
