Learn music theory with Sonid

The triad section is broken and unpassable. The exercise asks you to build a full triad, but the app won't let you register three notes (section two) — so a correctly placed chord gets marked wrong every time. Entering the notes one at a time doesn't help either; it still counts a right answer as wrong. There is no way to complete the section, which means there's no way to progress in the app at all. This isn't difficulty, it's a straight-up bug that makes the core lessons unusable. I liked the one-concept-at-a-time approach up to this point, so fix the triad input and I'll gladly raise the rating. As it stands I can't recommend paying for something you can't actually finish.

This app is amazing for training you on music theory concepts. it’s very engaging and the content sticks pretty well! My one annoyance is the app can get pretty laggy and sometimes you’ll press a button several times thinking it didn’t register and then they’ll all happen at once after causing you to input the incorrect answer on accident. i think you shouldn’t be able to press submit if you haven’t answered the question yet.

The lessons are keyboard based, but the keyboard is tiny and the app cannot be viewed horizontally. I am on the major second section, and am asked to play two notes, but there is no sound when I play them. The explanation of major second is confusing. Why is it a major second between C and D, two semi-tones between, and also E and F, one semi-tone between? You cannot advance to other levels without passing earlier levels. The pace of this app is excruciatingly slow. The C is always present on the keyboard, which is not real life and I would like the option to turn it off.
