I own dozens of iOS synths - I thought this one was basically a toy. Turns out it has a really deep and varied range of sounds. It even has sub-oscillators for some mean sounding basses. There are presets, and you can save your own tweaked sounds as well. Best of all, it has a useful touch grid interface that you can set to a scale and even control whether it snaps or slides to in-key notes. AudioBus compatability makes it a useful sketch tool, or a fun 3-minute distraction. Awesome!
