Show HN: I made a guitar solo improvisation app

Hi HN,

As a beginner guitarist who loves guitar solos, it felt amazing when I improvised over a backing track with a pentatonic scale. I wanted to make it easy for any beginner to pick up the guitar and start jamming solos, so I put together Guitartonic. I plan to add more features as my personal learning journey unfolds, and I'd love feedback from other learners as well as experienced musicians.

Happy jamming!
