When using our mice on an iPad or iPhone with AssistiveTouch the scroll wheel uses Apples "Natural Scroll" setting, which reverses all scroll outputs.
Unfortunately it is not currently possible to change this setting, as AssistiveTouch does not offer any options to modify scroll behavior.

This does not apply to the remote desktop apps which support our pen-grip mice. These generally use the default Windows scroll direction, and some provide the option of to reverse it.
