Field notes
The practice flow is organized into four areas: ear, chords, playing and progress. The homepage describes exercises across all twelve keys, a backing trio in styles ranging from swing to 12/8 slow blues, and a daily summary with practice minutes, streaks and reading scores. It also says app data stays on the device and no account is required; separate browser-based tools and short guides are available from the site.
