  Hello HN, this has been my personal project for quite some time now. It has been a slowly evolving project over the years and its core function is for users to expose themselves to progressively more difficult lessons of music notes. NOTE: It is free and there are no ads. There is an in app purchase but most of the app doesn't require it.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.

  isometric.nyc – giant isometric pixel art map of NYC▲1,325
