Store description excerpt

Whether you are playing your first notes or working through intermediate repertoire, Croak: Piano Teacher meets you where you are. Built for iPhone and iPad, the app listens as you play, adapts to your level, and gives you immediate feedback on every note, so every practice session is as productive as possible. REAL-TIME NOTE DETECTION Croak uses on-device machine learning to identify the notes you play through your device's microphone in real time, polyphonically, meaning it can detect multiple notes at once. No MIDI cable. No external hardware. Just sit at your instrument and play. The detection runs entirely on your device, with no audio ever sent to external servers. SIGHT-READING EXERCISES Sharpen your reading skills with dynamically generated exercises. Notes, key signatures, and clefs are selected based on your current proficiency level and gradually expanded as you improve, from natural notes in C major to accidentals across all major keys. Each exercise is graded on both accuracy and response time, giving you an objective measure of your progress after every session. MUSIC LIBRARY Practice with real pieces across six genres: Classical, Pop, Rock, Jazz, Children's Songs, and Holiday music. Each piece is presented bar by bar, so you can focus on the sections that need the most attention without losing your place in the score. Save your favorites for quick access at any time, and pick up exactly where you left off. ADAPTIVE LEVELING Croak tracks your accuracy, response speed, and session streaks across every exercise to calculate a proficiency level from 1 to 10. As your level rises, exercises introduce wider note ranges, new key signatures, and greater rhythmic variety. The system rewards consistent practice with streak bonuses and keeps a full history of your sessions so you can see exactly how far you have come.
