Q1: How much practice does it take to sing high notes?
Answer: In my experience, people often begin to notice a change after about three months of practicing ten minutes every day.
Q2: Can the app alone help me sing high notes or use my preferred voice?
Answer: The lessons are designed so you can develop various voices using the app alone. Some people say YouTube exercises alone gave them high notes or mixed voice, but I think those cases are fairly uncommon.
Q3: The audio examples in level-based practice are quiet. What can I do?
Answer: Yes. Try these volume settings. If they do not help, please contact us.iOSFrom the Home Screen, open Settings → Sounds & Haptics.If Change with Buttons is off under Ringtone and Alerts, the iPhone’s side buttons can adjust app volume separately from ringer/call volume.AndroidFrom the Home screen, open Settings → Sound & vibration.Adjust the Media volume slider to change the app volume.
Q4: Paa seems to receive different evaluations in introductory and beginner lessons. Do the criteria get stricter as lessons progress?
Answer: Yes, the evaluation criteria become stricter as lessons progress.
Q5: My voice seems the same, but the scores vary.
Answer: Voice assessment is about 80% accurate, so some variation occurs. The system is designed to vary less around C2; try adjusting your voice to C2.
Q6: The front camera starts automatically in level-based practice. Could anyone be watching?
Answer: No. Nobody, including the developers, can view it. AI automatically checks whether your mouth follows the lesson instructions, and the images are not stored on the server, so they are not available for anyone to view.
