I'm looking for an easy to use beat/drum app for IOS and Mac to find some rhythms as inspiration for writing to.

I'm a singer/songwriter/guitarist and not a drummer so I don't find it that easy to program beats/grooves myself. I'm looking for something that is super easy and user friendly to get going with, and has beats which sound like a drummer could have played them. Looking to use it mainly as a songwriting tool.

Any recommendations would be appreciated.
