Drum rudiments trainer - DRT app analytics for January 6

As a beginner drummer myself and having some programming skills I've decided to create mobile application, where I can get easy access to paradiddles and other rudiments in a library with clearly visual representation, on/off metronome and training time statistics for each rudiment in a set. App designed for both beginners and experienced drummers. Hope it will be useful to other people as well. Reasons to try: - Easy and intuitive controls - No need to know drum musical notation - Vertical musical tracker-type visual representation - Dark theme to save your device battery - BPM constant and acceleration modes - Prevention of display sleep mode when training - Slightly different snare sound samples for left and right hand strokes - Different normal, accents, flam and drag stroke sounds - Metronome sound and visual blink option with individual volume control - Time stats for every rudiments and overall training time - BPM from 10 for very beginners to 320 as hell - Count-in option - Metronome sound only mode - Drums sound only mode - Silent mode - Chance to training with no pad and sticks - just your hands and knees - Small app file size - Sufficient font size for people with eye issues - Rudiment editor with random shots generator
