One star for the effort. This is just another toy drum app so the only real app for a REAL drummer to play /tap with on IOS remains "IGOG" so get that app instead. A pro drum app seems such a simple thing and yet no one seems to be able to do it truly right! PROS: Nice 3d rendering of a kit CONS: -No touch sensitivity -No independent volume for each sample -No use of custom samples -No midi recording or playing -Drum sticks are actually in the way and totally annoying -kit should instead be top down view or pads and even have custom kit build and placement for much better interactivity/ useability . -Samples should and could have been far greater -FX levels should be mixable with dry etc -Jam along to track has no volume settings apparent -Real "pro" drummers never tested this app. I call that claim BS (But, app could be made good if all these obvious cons are addressed so hopefully they read this one day) SUMMERY: Does IOS really need another toy drum app? Nope. I sacrificed so you the reader neednt bother now move along until they upgrade this app with the necessary missing features.
