It's Not A Negative No
Unfortunately Apple doesn't allow downloads directly through their iOS system, so files can't be downloaded directly on devices like iPhones or iPads. I'm sorry about that! .On the bright side, Apple does kindly allow you to purchase my work directly onto a computer and transfer it to your iPhone or iPods.
Otherwise, musician's could collect a buck for a song without cutting in Apple or some other adorably named music store. And that wouldn't be fair.
