My favorite thing with vuKNOB is that is for free and with no ads and one of the most complete apps there is for Android. My second favorite thing is the JAM window and playing with arpeggiators that can be recorded and manipulated using one of the sound generators including a sampler. Well now it has the possibility outside of the scales that was already included to roll your own.
