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. WITH PREMIUM • All 295 levels across tutorial, practice, standard, challenge, and recap stages — a real curriculum, not endless random drills • The full C2 to C6 range, adding bass clef • All 11 beat-synced songs Premium is available monthly, yearly, or as a one-time lifetime purchase. 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

Learn to read music in five minutes a day. Free, with no ads and no subscription. Zebra turns music theory into 20 short games you'll actually open again tomorrow — from naming your first white key to reading two clefs at once. START WHERE YOU ARE A guided path of 41 lessons takes you through the keyboard, the staff, rhythm, intervals, scales and ear training. Every lesson ends with a game that asks for exactly what it just taught. Nothing stays abstract for long. FIVE MINUTES IS A REAL SESSION Each game is a short round with instant feedback: the note turns green when you're right, red when you're not. Play one round waiting for the bus and you've made progress. Play five and you've hit your daily goal. 600+ LEVELS, SO YOU WON'T OUTGROW IT Twenty games, each with its own ladder. You start on white keys and note names. Further up you're sight-reading a scrolling score, building scales in every key, and writing down rhythms by ear. WHAT YOU'LL TRAIN • Note recognition — on the staff, on the keyboard, by name • Sight-reading — notes scroll, you play them in time • Rhythm — tap the beat, hold the long notes, take rhythmic dictation • Intervals and chords — recognize them and build them • Scales and key signatures — major and minor, every key • Two clefs at once — treble and bass together • Real melodies — play tunes you know from the very first chapter WHAT KEEPS YOU COMING BACK • A daily challenge, the same one for everyone, every day • Quests and a streak that rewards showing up • Stars, unlocked games, and a skills chart that shows what's lagging • Statistics on every game, so progress is a number and not a feeling ALSO INSIDE • A free piano and a metronome, always in your pocket • Works fully offline, on the plane and in the practice room • English, French, Spanish, Italian and German NO ACCOUNT. NO ADS. NO PAYWALL. Everything is in the app from the first launch. Nothing is unlocked with money — only with practice. MADE FOR Piano, guitar, violin, brass and voice students. Music school pupils. Self-taught musicians. Teachers looking for drills. Anyone tired of counting lines on the staff. Open it, play one game, and find out where you actually stand.
