How Make your own song with an app?

I want to know if there's an iPhone app that let's you record yourself a lot of different times, then put it together as one… Like make a song without beats?

I don't think there's an iPhone app for that, but i know a different way to make a song like that:
record yourself on the computer; make however many recordings you want.
then go to soundation or another site/program you can make music, and you can upload the files
or, record yourself on the actual site
