There's also the question of target market. Android may have huge market share globally, but I'm going to guess that among the target market for the H9 – people with enough disposable income to afford a $500+ effects pedal – the gap is significantly smaller, and might even be iOS-dominant. The fact that most guitar-processing hardware that interfaces with mobile devices is either iOS-only or shows significant lag in rolling out Android support, I'd argue, tends to bolster that hypothesis.
