About
PitchCompass is a powerful pitch detection and ear training tool designed for musicians, vocalists, and music students on iPhone and iPad. Using the device's built-in microphone, it captures live audio and displays the detected pitch in real time on a clear, intuitive circular chromatic interface showing all 12 notes simultaneously — making it instantly obvious whether a note is sharp, flat, or perfectly in tune. The app features two detection modes: Fast Mode offers low-latency feedback ideal for live tuning and performance monitoring, while Accurate Mode applies more intensive analysis for precise pitch detection during detailed ear training sessions. Users can tap any note on the display to hear a reference tone across four octaves, enabling side-by-side pitch comparison and aural skill development. Customization options include light and dark display modes, a choice between Do–Re–Mi solfège or C–D–E letter notation, an adjustable A4 reference frequency (around 440 Hz) for accurate instrument calibration, and a noise floor control to minimize microphone background interference. PitchCompass is well-suited for intonation practice, instrument tuning, pitch stability monitoring during rehearsals, and music transcription. It is designed for all skill levels — from beginners building pitch awareness to professionals refining their intonation. The developer collects no user data, and the app is available for a one-time $12.99 purchase with no in-app fees.
