Practicing a song usually means juggling tools: one to isolate a part, one to slow it down, one to record over it, one to write it down. Many are paid, online-only, or make you upload your music. underdaw does it all for free on your own device: split songs into stems, mute or solo any part, change speed and key, play with a song-synced metronome, record over the backing, and read tab that scrolls with the original recording.
