Works but frustrating

I think this app has what a lot of musicians are looking for and need, however regarding the tonal drones, they dont seem to respond when I tap on them and its frustrating. It either takes a while to turn on after tapping it 5-6 times and sometimes it just wont despite all my efforts. I know this happens on the iPad version and IPhone version. Please fix.
