What a dedicated jazz practice app should help you do
A useful jazz practice app should reduce setup time and keep you close to the musical task itself. If adjusting tempo, loading a chart, or repeating a section takes too much friction, you practice less and lose focus more easily.
Chord Progressions combines built-in tunes, category-based backing tracks, custom chord-chart playback, and rhythm-section control so you can move between exercises and real tunes without changing tools.
