Unlock the musician in you with Harmony. Whether you're a beginner or a seasoned player, Harmony trains you to recognize, read, and play music. Four domains, one method: theory becomes a game of focused exercises you tune to your level. The 4 domains • Notes — spot and place every note. • Intervals — measure the distance between two pitches. • Scales — major, minor, modes, and more. • Chords — from triads to extended chords, inversions included. Three ways to train • By sight — read the note straight off the staff (treble or bass clef, key signatures, ledger lines). • By ear — hear a note, interval, or chord, then identify it. • By playing — play the target back on an interactive piano. Play your way • By touch, on the virtual keyboard. • By microphone, singing or with your instrument. • By MIDI, plugging in your keyboard (USB or Bluetooth). Track your progress • Short sessions — choose how many questions, and get your precision at the end. • Clear statistics — your mastery domain by domain, by question type, and by concept. • Your practice day streak, to keep the rhythm going. Why Harmony? • Tailored — pick the concepts, question formats, and difficulty. • Easy to get into — a guided tour shows you the essentials on first launch. • Distraction-free — a clean interface built for focus. • On every screen — phone and tablet alike. • Offline — everything works without a connection. • Multilingual — English, French, Spanish, and three note notations (Do-Re-Mi, C-D-E, German notation). Harmony is just getting started. We improve it every day to build the most complete training companion, from theory basics to a trained ear. Happy practicing!

Glozzer is a singing-technique notebook, made for people who love to sing and want to nail a song line by line. Paste in your lyrics and mark how to sing every word — drop in purpose-built symbols for accent, breath, resonance, articulation, and more with a single tap. ■ Key features ・Mark right on the lyrics: purpose-built symbols for accent, breath, resonance, glissando, articulation and more, aligned precisely to each word. ・Organize in layers: your teacher's directions and your own practice notes each get their own layer — show or hide them, so nothing gets in the way. ・Workspaces and folders: sort different songs and different stages of progress into their own place. ・Practice notes and warm-ups: jot down what mattered in each session, your warm-up routine, and your range. ・Share in one tap: copy the parts you choose into a brand-new workspace to share with a student or friend — the two stay separate, so neither affects the other. ・Start as a guest: no sign-up needed; when you want to keep your work across devices, sign in with Google or Apple. ■ Who it's for ・Anyone learning to sing: keep every line's technique cues on the lyrics, so they're clear the moment you practice. ・Singing teachers and classes: turn spoken guidance into marks students can actually read and take home to practice. ・Self-taught singers: capture the techniques you pick up and your own insights, all on the song itself. ■ Your content, your call The text you paste and the marks you make are stored safely in your account, ready to pick up across devices. This is your private content: we don't provide a lyrics database, we don't source lyrics from third parties, and we never make your content public or share it — and you can delete it anytime.

Verdict
The clearest difference is update cadence: Glozzer at every 2 days against Harmony's every 3 weeks. Harmony's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
