Most valuable bass tool

Having a percussion app like this has contributed immensely to my skill-building exercises. As much as they talk about drums in the tutorials, everything mentioned can be applied towards my practice sessions. Working on it but Im sure I can replicate Neil Peart. Interested to see if I do this, then displace the accents, what kind of madness will come my way.
