Features & Capabilities

Sonid is a music education app that teaches music theory by focusing on one subject at a time. This focused approach helps you absorb new material more naturally. It covers notes, intervals, scales, chords, and progressions, with questions, adjustable difficulty, unlockable modules, XP, badges, and an in-app forum for help.

It’s designed for both beginners and experienced players who want to broaden their musical horizons. Look up terms anywhere in the app, display notes for scales, chords, or intervals in the playground, and learn without ads with Sonid Plus, which unlocks extra exercises, detailed statistics, and ad-free learning.

User Reviews

Multiple reviewers praise Learn music theory with Sonid as engaging and effective for building theory knowledge, with solid ideas and value from a free version. However, a dominant recurring issue is unreliable audio playback across devices, with sounds failing to play, stuttering, or disappearing. A few reports touch on performance problems and occasional confusion, but the core learning content remains appealing for many users. Overall, the app's strengths are its instructional concepts and user engagement; its weakness is inconsistent audio that hampers practice.

Pros

Engaging and effective for learning music theory; concepts stick.
Great ideas for music theory concepts and instructional design.
Users recommend the app and view it positively.
Free version provides good value and can lead to paid upgrades.

Cons

Audio playback issues: sound not working or inconsistent playback.

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.
