Need help with the tuner, metronome, reference tones, or analysis? Email support@cybrpulse.com. Please include your iPhone model, iOS version, and a short description of the issue.
The tuner and analysis need microphone access. Tap Start tuning or start analysis, then allow access when iOS asks. To change permission later, open iPhone Settings → Privacy & Security → Microphone and enable Practice Studio.
Check the iPhone volume and audio output, then stop and start the tone or metronome again. If the issue continues, email us with your device and iOS version.
