Common questions
The app says it cannot hear me clearly
When the microphone can't pick up your voice clearly, Croonia tells you instead of guessing a score. Put on headphones and move somewhere quieter, then try again.
Do I need an account?
No. Croonia works without an account and without an internet connection.
How do I turn the microphone back on?
On your iPhone, open Settings, scroll down to Croonia, and turn on Microphone.
How do I delete my data?
Everything Croonia keeps is stored on your iPhone. Delete the app, and all of it is deleted with it.
Which iPhones does Croonia work on?
Any iPhone that runs iOS 26 or later.
Singing hurts. What should I do?
Stop singing and rest your voice. Croonia is a practice app, not medical advice, and it cannot hear strain. If you are hoarse for more than two weeks, or it hurts to sing or speak, see a doctor or a voice professional.
