Show HN: Cadence – A Guitar Theory App

Hello HN, I just released this guitar theory and ear training mobile app 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.

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.
