Most note-reading apps drop you into 35 notes on day one. StaffReader starts with one: G. You earn the next note when the first one is automatic. THE PROBLEM WITH OTHER APPS Someone I know practiced note reading every day for a week and hit 6% accuracy. That's not a memory problem — it's a design problem. When you have no anchor, you guess. Randomly. The app marks you wrong and moves on. Nothing sticks. HOW STAFFREADER IS DIFFERENT Stage 1 is one note: G4. The treble clef literally wraps around that line — the clef exists to point at G. You drill it until you recognize it in under half a second. Then you earn Stage 2. Stage 2 adds C5. Now you have two landmarks. Everything between them — A4 and B4 — is just a step from something you already know. Stage 3, 4, and 5 expand outward from your anchors. By the time you reach the full treble clef in Stage 8, every note is familiar because you arrived at it from something solid. This is the landmark note method — what music teachers have used for decades. StaffReader enforces it. THE PROGRESSION Stage 1 — G4 (one note; the treble clef points here) Stage 2 — G4 + C5 (two anchors) Stage 3 — G4, C5, A4, B4 (fill between anchors) Stage 4 — adds E4, F4 (expand downward) Stage 5 — adds D5, E5, F5 (complete the octave) Stage 6 — adds Middle C (C4) — your first ledger line Stage 7 — adds G5, A5 — ledger lines above the staff Stage 8 — accidentals: sharps and flats on notes you already know Stages 9–15 — two-note intervals, then 3-, 4-, and 6-note melodies You advance by hitting 90% accuracy — not by waiting for a timer. The note has to be automatic before you move on. WHAT YOU GET FREE Stages 1, 2, and 3 are completely free. No ads, no credit card, no subscription. That covers G4, C5, A4, and B4 — four notes that anchor the entire treble clef. FULL CURRICULUM Stages 4–15 unlock for $4.99, one-time — intervals and melody reading included. Bass clef gets its own track, same method, starting from F3. Every future update included. No subscription, ever. DESIGNED FOR ADULTS WHO'VE TRIED AND FAILED If you've opened a note-reading app, felt overwhelmed, and closed it — StaffReader is designed specifically for that experience. Short sessions (about 60 seconds). One note at a time. Progress that's measurable. It also works for children learning with a teacher, and for musicians who play by ear and want to add notation literacy. PRIVACY No account required. Anonymous usage analytics and crash reports only — nothing personal, never sold. Works offline.
Quick Theory

Quick Theory teaches real music theory the way a friendly teacher would: one small idea at a time, with your hands on the answers. TYPE THE MUSIC No instrument needed. You answer with a letter keyboard — A to G, sharps and flats — and quick taps. The piano on screen is your teacher's piano: it plays and shows, you listen and spell. EIGHT COURSES THAT ADD UP • Introduction to Music Theory — the twelve notes through scales, keys, intervals, chords and progressions • Introduction to Music Theory, Part Two — minor for real, pentatonics and blues, inversions, sevenths and cadences • Reading Rhythm — note values, time signatures, and counting that sticks • Ear Training, Part One — from "up, down or same" to hearing a melody's shape and finding home • Chords by Ear — scale degrees, chord colors, bass lines and cadences • Advanced Chord Construction — build any chord in any key, decode any symbol on a chart • Guitar Theory, Part One — the fretboard map, CAGED, barre chords, and your first improv map • Songwriting — verses, choruses, hooks, prosody, and finishing the song EAR TRAINING DRILLS Six configurable drills that build the ear behind the theory: Interval Recognition, Melodic Dictation, Chord Progressions, Chord Qualities, Scale Degrees, and Meter Detection. Set the range, the speed, and the answer surface — solfège or piano — and practice exactly what you're weak at. A TOOLKIT THAT COMES WITH IT Look anything up: Chords, Scales & Progressions, Circle of Fifths, Scale Fingerings, Alternate Tunings. Practice with a Tuner & Pitch Pipe, Metronome, Slow Downer, Piano, Sight Reading, Random Note, and Jam Along — a band that loops while you play over it. Write with Lyric Studio, Melody Helper, Riff Recorder, and Tab Studio, a full guitar tab writer that plays back and exports. MISTAKES ARE PART OF THE PLAN Wrong answers get real explanations — not just "incorrect." Miss the same idea twice and the app changes how it asks. Genuinely stuck? The lesson steps aside, tomorrow it invites you back, and nothing guilt-trips you in between. SPELLING COUNTS A-sharp and B-flat share a piano key but mean different things. Quick Theory is the rare app that teaches you why, gently, at exactly the moment it matters. MADE TO RESPECT YOU No account. No ads. No tracking. Lessons and tools work offline, and your progress, songs, lyrics and recordings sync through your own private iCloud — only you can reach them. Speed Rounds review what you've learned, a Weak Spots quiz targets what you keep missing, and a lenient streak celebrates showing up and forgives a missed day. Whether you sing, play, produce, or just want to finally understand what "the key of F major" means, Quick Theory gets you there a few minutes at a time.
