The app comes with me now on two devices to use, and I am absolutely satisfied. The app itself has already earned more than five stars, counting still support it, I would be 50 or more stars. Whether a hobby DJ you now like me, or a professional DJ, this app leaves no wish unfulfilled. All the effects which are available in the Premium version are the hammer, this app is more than worth the money !! And the support is at least as good. I had an answer on the same evening, which is definitely not standard and must be praised !! All in all, I can only recommend the APP. I am looking forward to other Apps by this developer !!! Two thumbs up and keep it up folks: D !!!
