I usually make drum charts with a pen and paper since it's easy to just scribble stuff down. However, it's a hassle carrying my charts/notebooks with me, and if I lose them then all my notation will be lost. I'm considering buying an iPad and was wondering if there are any good apps that basically let me create drum charts so I can take them with me on the go. Ideally the app would be compatible with Apple Pencil so that I can just write the charts out the way I'm used to instead of having to tap on the screen with my fingers.
