App like audacity for iphone?

Hey, basically I need an app for ios (iPod touch, iPhone, iPad) that can let you record over yourself multiple times like audacity. I don't need any of the other effects though they would be nice, but i basically need it just so you can record multiple tracks that can be played at the same time. I kind of need it to be free as well. Thanks! :)

This might help you out…

Hope this helps.
Have a nice day!
