Notes Ninja turns learning to read music into a fast, satisfying game. Slice the correct notes as they fly toward you in time with real songs — no instrument, no microphone, just your fingers and the beat. 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. WHAT YOU GET FREE • The first 15 levels — tutorial, practice, and standard stages • Treble clef notes C4 to G4, the core of early note reading • Beat-synced gameplay with real music • No ads, ever Enough to learn to read your first notes and decide whether the game is for you, before paying anything.

IN EVERY VERSION • English, German (H), and Solfège note naming, switchable to match how you were taught • Slice-to-learn gameplay — swipe only the correct notes; wrong slices cost a life, so every note matters • Adaptive difficulty (slow, medium, fast) that grows with your skill • Combo scoring — chain correct slices for bonus points • Daily goals and streaks to build a practice habit • Achievements plus global and weekly leaderboards • Power-ups — shield, double points, extra life — when you need a little help • A dedicated practice mode, separate from scored levels • Guided tutorial onboarding — no music background required to start • Short sessions that fit a school-night practice routine WHY NOTES NINJA Most note-reading apps are flashcard drills, or they need a piano, keyboard, or microphone to check your answer. 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 • Kids starting music lessons who need note-reading reps between classes • Parents looking for screen time that's actually teaching something • Adult beginners picking up an instrument who need to get fast at reading notes • Homeschool music education and general practice • Anyone who reads music in German H notation or Solfège 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

NotesNinja's advantage is ads (none vs shown) and iOS requirement (16.0 vs 18.4). On price and device support there is nothing between them.
