Hello HN, I just released this music theory and ear training mobile app for guitar which I've been working on for a bit more than a year on the side.

The idea was to make something for the eternally "intermediate" guitarist (myself included). There are a lot of beginner apps which rely on learning songs, toolkits which give you a bunch of stuff with no explanation but not many in-between apps to actually learn and practice more generic and somewhat advanced stuff.

The app contains short lessons, recaps and most importantly challenges (visual, audio and pure theory) along with a very complete library.

The challenges are made for practicing, they will get increasingly harder and getting to the max score is supposed to be quite hard. The idea being that you have to repeat them regularly until your brain has integrated the info and it flows naturally rather than being a one time quick dopamine shot. This is partly inspired by how language learning apps work.

It has no ads, a lifetime purchase option and you can use it without an account if you don't care about multi-device sync or backing up your progress.

Just tried this out and I’m loving it, especially the UI/UX. The welcome screen animations are great, they make the onboarding feel smooth and polished. I love that the navigation icons show labels when active, so you always know where you are.

The built-in tutorial on the Learn screen is a really nice touch, and the Library is genuinely useful (I’ll definitely be using it for scales and arpeggios).

Also, the Go Premium page is clean and the pricing feels refreshingly fair. Awesome stuff!

Two quick questions too:

– What did you use to build it? The UI/UX feels super slick, it’s fast and smooth on Android.

– What were your biggest hurdles during the build? Not just technically, but overall. For example, was it tricky learning enough music theory to validate the content, or was getting it live on the app stores as a solo dev the harder part?

I might have to try it out. I got an interactive music theory course (Lightnote) built by another HN user after reading the "2024 side project show and tell" [1]. It seems to be in a similar vein, though with less emphasis on guitar. Maybe with both I could have theory and practice, so to speak.
