I've used Logic most of my life, but Garageband is pretty great these days on iOS/mac. And you can transfer the projects to Logic if you want to take them further. A couple of niggles (can't set start/end points for loop playback/recording, no midi learn, relatively few keyboard shortcuts) but for a free portable DAW it's superb. Supports a lot of i/o too, I've used interfaces all the way from 2 track IK duo pro to 16 channel Soundtrack desk with it.
