Poor accessibility
Hard to control when even one degree difference of your finger swipe triggers an entirely different control. This makes setting up more than one control a nightmare. Just awful for anyone with shaky heads bc PTSD, tremors, mental disability etc. And the sound effects in-app are so loud they scare you when you are adjusting something, but if you turn it down you might sleep in.
