Read music at a glance—not one note at a time. NoteFlash turns note reading into a fast, daily flashcard workout. See a note on the staff, tap the answer, and repeat until every note is instant. No more counting lines from the bottom. ■ WHO IT'S FOR - Beginner pianists who freeze when the sheet music comes out - Parents teaching kids their first notes - Choir, band, and orchestra players who want to stop guessing - Returning players whose note reading got rusty - Anyone starting solfege or music theory and needing solid fundamentals ■ WHY YOU STILL COUNT LINES Slow reading isn't a talent problem—it's a method problem. If you decode notes one by one, you'll never keep up with the music. Fluent readers recognize notes the way you recognize words: instantly, on sight. NoteFlash builds that reflex with rapid-fire flashcards. ■ SEE IT. TAP IT. NEXT. One note appears on the staff. Tap the answer and the next card is already waiting. Each question takes seconds, so a meaningful session fits into a bus ride or the five minutes before practice. ■ ANSWER YOUR WAY ▸ Solfege buttons (Do–Re–Mi) — friendly for absolute beginners ▸ Piano keys — connect each note to its place on the keyboard ▸ Full keyboard — rotate your phone for a 3-octave piano layout, closest to real playing (Premium) ■ YOUR WEAK NOTES SHOW UP MORE NoteFlash tracks your accuracy on every single note and weights the deck so your problem notes appear more often. No wasted reps on notes you already know—and you can check your per-note stats anytime. ■ RHYTHM AND CHORDS, TOO ▸ Rhythm mode: identify note values—quarter notes, eighth notes, and more (Premium) ▸ Chord mode: read triads as a single shape (Premium) Pitch, duration, and harmony—all trained with the same fast flashcard flow. ■ MAKE IT A GAME ▸ Time Attack: how many notes can you name in 60 seconds? ▸ Endless: keep going until you miss Beat yesterday's score, and daily practice takes care of itself. ■ TREBLE AND BASS CLEF Treble clef training is free. Go further with bass clef, sharps and flats, and the upper register as you level up (Premium). ■ HEAR EVERY CORRECT ANSWER Correct answers play a real piano sound, linking the note you see to the pitch you hear—a head start for ear training as well. ■ ONE-TIME PURCHASE. NO SUBSCRIPTION. Premium unlocks bass clef, sharps & flats, the upper register, chord mode, rhythm mode, and the full 3-octave keyboard—forever, with a single purchase. Start free with treble clef today. --- Fluent reading is the skill that makes every other part of music easier. Download NoteFlash and start reading at a glance.
