The Covert Conversation plugin works on mobile - but was not built for mobile so there may be some limitations… i.e. the ad will be small and the sound may not play.
We are compiling a list of feature request and this has been added to the list of possible new features.
We can't promise if or when we will do it.
But we can promise that we are working hard on improving the product.
Remember that you get free life time updates :)
