Perfect!! 

I play trumpet and this works so well!! I can here the beeps even while playing!! I also luv the "tap tone" feature because if I dont know the tempo, I can just tap it and it tells me what it is. I also luv how it has a different beep than the others when it goes to the 1st beat out of how ever many beats per measure!! This is a very useful app for me and really helps me stay on beat!! Its the best one Ive tried and ITS FREE!! a must have app for any musician!!
