Drum rudiments trainer - DRT

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
