Recording Software for Android?

I'm not quite sure if this is right location for this thread but I'm sure if there is somewhere more suitable i'm sure it will get moved.

What I am wondering if there are any apps (preferably free) that I can use to record more than one track on, to be honest two track recording would probably do.

I just want to record demos so I can work out lyric ideas for my songs. I mean if such an app doesn't exist I can always just record my guitar and whatever lyrics I have so far, it's just so I can get an idea anyway.

I would normally use Audacity on PC but my laptop currently isn't usable and plus my tablet is handier. I could use Wavepad but that only does one track.

I'm using a Samsung Tab 4 (7 inch) if that any use.
