Drum Rudiments Trainer - DRT is a free Android app designed for both beginners and experienced drummers. Created by SeaBream, the app offers an extensive library of paradiddles and other rudiments with a clear visual representation, on/off metronome, and training time statistics for each rudiment in a set.

The app's easy and intuitive controls make it ideal for anyone looking to learn drumming without having to know drum musical notation. The vertical musical tracker-type visual representation, dark theme, and prevention of display sleep mode during training make it an excellent choice for drummers who want to save their device battery.

The app also features different normal, accents, flam, and drag stroke sounds, and slightly different snare sound samples for left and right hand strokes. The metronome sound and visual blink option with individual volume control, BPM constant and acceleration modes, count-in option, metronome sound only mode, drums sound only mode, and silent mode make it an all-in-one app for drummers.

The app also offers a chance to train with no pad and sticks - just your hands and knees. The app's small file size and sufficient font size for people with eye issues make it a must-have for any drummer looking for a comprehensive training app.
