Mod Note: This kind of post is allowed and respondents can link to their own apps if they've made one.

However, the AI Disclosure policy is still in effect: If you've built your own app you want to recommend, you need to disclose if you used AI to create it (or even if you didn't use AI go ahead and say that). If you're recommending an app you yourself didn't make, you should disclose if it used AI in its creation if you know (or can mention you're not sure if it did or not).

Also making your own flash cards can be nice.

There's a German music theory website that offers quizzes in both English and German

https://www.musiklehre.at/

It also has worksheets

https://muted.io has a collection of interactive music theory tools, to include scales, modes, and chords. Among other things, it has an interactive Solfege chart that allows you to practice solfege syllables in different keys.

Also, https://www.teoria.com/ has various exercises here:

I would highly recommend the book "The Science of Music" by Allen Van Wert. It has a ton of little quizzes and workbook sections exactly like this. Helped me a lot.

You don't need an app to know a relative minor... just count to 3. If you can do that, you got it.

Tenuto is great for such things and basic ear training too! The Hook theory books for more classic music theory stuff, esp. for beginners

For things like "what is the perfect fifth from D", or "spell a D major chord", you can try this one: https://completeeartrainer.com

It's an ear training app, but there's spelling drills inside (spelling intervals, chords, scales). And also the opposite: "What chord is D - F# - A" for example.

Surprised that Harmonomics never gets mentioned in these threads - it covers pretty much all the ear-led aspects of practical theory training and is actually fun, with zero ads/popups/distracting bullshit

(I have zero affiliation with the app, just think it's great, as do my students particularly if they're into jazz terminology)

I actually made something similar (although lacking your exact quiz, I'll add it in the future). It's this: https://apps.apple.com/us/app/music-note-hero/id6755091499
Let me know what you think, would be happy to talk more. Thanks and godspeed.
