Practice Studio is an iPhone app from CHAPPIE LLC for tuning instruments, keeping time, playing reference tones, and viewing live sound analysis.
The app requests microphone access when you start the tuner or live analysis. Microphone audio is processed on your device to calculate pitch and show the analysis displays. The app does not record, store, or transmit microphone audio. You can stop microphone use in the app or change its permission in iPhone Settings.
The app does not require an account, display ads, or include analytics. It does not send personal information or audio to CHAPPIE LLC or third parties. Practice settings and metronome presets are saved locally on your device.
