I havent tried the related app yet because using Poweramp to turn up the volume even more works for me. While I may sound extremely positive because I do think this keyboard is fantastic, I will be giving it a 4 star because my media controls are not programmed correctly or something. Cumbersome to put on. Says a lot for those inserts, just bought 3 more pairs while the price is low. In fact, they make me love my earphones even more. Also, the extras in the box were a pleasant surprise. The hdmi port has to be tried several times before it can be connected. The carrier was easy to install to the roof top and the waterproof material was important for rainy weather. The further you extend the center the more sag you will see in the poles. still looks and sounds brand new despite many trips to the beach and to poolside and a hundred times around the house.
