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.

(This is my second and last post about this sorry for spam. My first post a few weeks ago didn't get any views and posting on a saturday might not have helped...)
Don't get me wrong, playing a piece like this cleanly and with such feel takes great skill and is probably not something I will ever be able to do but I mean easy in the sense that you can quite clearly see the path to take to get there (or halfway there). "Just" learn the piece slowly block by block, then repeat it for hundreds of hours without much thinking until it flows by itself (I'm simplifying but you get my point).
On the other hand, while theory can be grasped quite fast, applying it to your playing, composing, and improvising with it has always felt to me like a multifaceted beast that you have absolutely no idea at which angle to tackle from. You just stumble your way around it until the pieces start clicking together and it's really hard to find a clear path to follow which makes it much harder imo, or at least more frustrating/blurry.
