Music Memos Free Made for iPhone

Optimized for acoustic guitar and piano, Apple’s app is a great way to record musical snippets and ideas for later development. (Think of it as like the Voice Memos app, but for instruments.) It waits for you to start playing before it records in uncompressed audio through your iPhone’s mic or via an external mic. It can detect the chords you play and lay down drum and bass tracks to your recording.
