The microphone went dead the moment the exercise began. The reference note that plays during the countdown was switching the listening off as it ended, so you sang the whole exercise with the app hearing nothing. Not any more. Thanks to whoever took the trouble to say so in a review instead of just deleting the app.

The session now has the shape of a class. A lesson that needs warming up opens a routine — breathing, lip trill, humming, the lesson, cooling down — and tells you why each step is where it is. The tuner can be used without looking. It speaks the target note and how far off you are, corrects you through haptics while you sing, and every chart now has its summary written next to it. At the accessibility text sizes nothing is cut off or overlapping any more. The screen no longer switches off mid-exercise. A home screen widget shows your streak and what comes next. German note names (H, not B), Russian solfège in Cyrillic, the French Ré, and Chinese jianpu. The listing screenshots are now in your language.
