Do I need to install anything?
No. SingTuner runs in a recent browser on computer, tablet or phone. You only need to allow the microphone.
Is my voice recorded?
No. Pitch is detected on your device while you sing. Only the results (which notes were in tune, and for how long) are saved to your account.
Can I use my MuseScore files?
Yes, through MusicXML: in MuseScore choose File → Export → MusicXML, then upload the .musicxml or .mxl file.
Who pays in a choir?
Only the person who creates the choir’s space, usually the director. Singers use a free account.
Is the app available in Portuguese?
Not yet. For now the app is in English, and the notes can be shown as Do-Re-Mi.
