Never imagined the app just so loaded because free and I wanted to see if that is really so useless, as the other reviewers write. Conclusion: The app responds as it should. It provides various drum kits and also several beats as a demo, which for laymen like me is a good guide. Moreover, it seems to me quite to give the opportunity to take pictures, but what I have not been tested. There is also a tutorial, where everything is explained. To those who have fun on the drums (of course without great sound experience) and a little more rhythm in their blood like me, I can wholeheartedly recommend the app (at least the Kindle Owners - in other Tablets I have not tested).
