An iPhone ear-training app runs daily interval, scale, chord, and cadence drills, then uses the microphone to check sung answers.

Musicians building interval and pitch-recognition skills
Worth noticing
Practice selection uses misses from the last 14 days rather than a lifetime error count.

Field notes

The practice model separates recognition from production: learners first identify a piano, guitar, or sine-tone sound, then reproduce it with their voice. Drill selection is based on misses during the previous 14 days, while sessions report streaks, accuracy, and a round summary. The page also lists iCloud syncing for progress, lessons, and badges, and marks Android support as coming soon.
