Built for true beginners: kids starting music lessons, parents supporting practice at home, and adults refreshing the basics. Notes Ninja trains real note recognition through repetition, instant feedback, and the pull of a good arcade game.

Notes Ninja is neither. It's a genuine slicing game where the only tool is a swipe. That makes it something rare: a note-reading trainer that feels like play instead of homework, backed by a real progression of levels and beat-synced songs instead of a loop of the same ten flashcards. PERFECT FOR โ€ข Kids starting music lessons who need note-reading reps between classes โ€ข Parents looking for screen time that's actually teaching something โ€ข Adult beginners picking up an instrument who need to get fast at reading notes โ€ข Homeschool music education and general practice โ€ข Anyone who reads music in German H notation or Solfรจge and wants an app that matches how they were taught Notes Ninja is free to download, with no ads in any version. Continuing past level 15 requires Premium. Learn notes. Train your eyes. Have fun doing it. Privacy Policy: https://notesninja.app/policy.html Terms of Use (EULA): https://notesninja.app/terms.html
