Today's review
The app knows what you are about to forget and brings it back at the right time. What is already solid waits longer.
Read, listen, practise and ask in one place. The app brings the site's topics and courses together with ear training that corrects you, explains why, and brings back what you are about to forget.

Each question plays as often as you need. A wrong answer is not just marked: it comes with the reason, in a musician's terms. Answered a perfect octave instead of a minor sixth? That is eight semitones, not twelve.
Build each drill your way, choosing what goes into it.
The app plays the question, listens to your spoken answer, tells you whether you got it and moves on. It works with the screen off and the phone in your pocket: on a walk, in traffic, with your instrument in your hands.

The site's own texts, made for the small screen. Every note mentioned plays and lights up on the keyboard, and every example is computed note by note, never made up.

The app knows what you are about to forget and brings it back at the right time. What is already solid waits longer.
Read and sing with the metronome keeping time and the piano giving the note. The microphone follows whoever sings.
How much you practised, what you get right and what has gone cold, concept by concept.
Ask in English or in Portuguese, typing or speaking. After a mistake, the tutor explains the confusion. Every chord and note it mentions is computed by the same engine as the site, and plays.
A metronome, a tuner, a keyboard that fills the screen and vocal warm-ups. Beside them, the site's harmony tools, to settle a question without leaving your practice.

Without a subscription you can already read, train your ear and use the tools. The subscriptions, monthly or yearly, are the site's own: subscribe in one place and you have both.
What you read on the computer and what you practise on the phone go to the same place.
