Rudiments is a free and simple app for practicing drummers. It allows you to create your own practice patterns. Create and store them anywhere you want, both manually and randomly. Practice patterns include all the basics of drumming, such as right and left hand control, with optional bassdrum beats. You can easily edit existing patterns or create new ones. You can add accents at any position, or include bassdrum beats as you wish.

You can use this app to create all your favorite practice patterns. Just use the buttons to set the position of the accents and the beats, and you are ready to go. The random button is customisable. You can set the amount of times the app will create a new practice pattern.
