Developer MSXII Sound Design has released an EP of tracks produced 100% on iOS. Joints Off iOS varies between experimental Hip Hop to Trip Hop. There is also an accompanying blog post, with details on how the tracks were made.
The tracks were put together in BeatMaker 3, and use their own Lo-Fly Dirt. Additionally you'll hear Audio Damage's Adverb2 & Discord4, Klevegrand's DAW Cassette and Tines; plus more from AudioKit, Moog, Korg, Akai, and IK Multimedia.
I try not to post SoundCloud embeds because they used to crash mobile browsers. I'm going to give this one a shot, and see if maybe they've fixed it. If you notice the site crash your browser please let me know in the comments!
