I'm a big fan of Hookpad as well as the theory tab database and trends explorer on the same site. The theory tab database in particular is surprisingly comprehensive though some of the tabs on there are incomplete. I also use chordified.net to help with deconstructing the chords of songs I discover and wanna learn to play/recreate.
Music Theory
A place to discuss and answer questions about music theory. All instruments are welcome, no question is stupid!
Hookpad looks like a cool tool to register ideas. Or am I not getting it?
Yeah it's a great tool for songwriting and it's usually my next step after the initial idea when writing a song. Whenever I hear a song I really like the harmony of I usually check the theorytab database, too, to see if anybody's deconstructed it. You can technically make full songs on Hookpad if you buy a subscription (or pay the one-time fee) since it has drums and other instruments, but I find that better to do in a DAW or with a band and just use Hookpad to lay down the initial structure.
The OpenEar app for ear training exercises. I should use it more often.

These types of Youtube videos for recognizing frequencies. It's exciting to notice the improvement from these.
I like to read Open Music theory. I think the explanations there are well done.
This is a great source with some good content written by scholars. If you find a topic that you want to learn more about, read the sources they cite. The form content is pretty good, but I would advise readers to go to the original sources (like Caplin’s Analyzing Classical Form: An Approach for the Classroom). The same could be said about many of the other topics. They provide good summaries and intros on open music theory.
musictheory.net has the most customizable exercises for drilling in notes, intervals, scales and chords, both from sheet music and from an ear training perspective.
Teoria looks fantastic for ear training. Anyone know of something for pure theory drilling? E.g. a site that would give me a root and quiz me on what the minor seventh would be?
You could use this part: https://www.teoria.com/en/exercises/ic.php. Teoria indeed always reverts around hearing what you do and reading it from formal notation. I think that's a reasonable design choice, but it of course goes beyond simply drilling intervals into you. To be honest, I used physical flash cards for the really basic stuff, like "What notes are in an E-major7 Chord?" I still have them and they served me very well. (:
