About this app
What Sight Staff does
Sight Staff is the offline sight-reading trainer for the 10 million US adults learning piano — the demographic Piano Marvel's $290 subscription locks out, Tenuto's 24 fixed drills bore, and Notevision's middle-C-equals-octave bug has frustrated for years. What Sight Staff does: — A daily 5-minute streak. A note appears on the staff. Tap the matching key on the keyboard at the bottom. Right answer plays the note. Wrong answer shows the correct key for half a second. — Adaptive per-note mastery. Each pitch on each clef has an Elo-style score. The app shows the notes you're worst at twice as often as the ones you've nailed. — Treble + bass + alto + tenor clefs. Switch clefs in a tap. Practice for ABRSM, RCM, or just to get faster at chamber music. — Ledger lines + accidentals. Up to four ledger lines above/below, sharps, flats, naturals. Difficulty unlocks as you master the easier notes. — Beautiful staff rendering. Drawn in SwiftUI Canvas — crisp on every iPhone screen. — Optional piano sounds. A bundled grand piano sample plays each note you correctly identify. AVAudioEngine, on-device, no streaming. — Daily streak that doesn't punish. Miss a day, your mastery scores stay. No "streak lost" guilt. — No account, no cloud, no subscription. Free, forever. Your mastery data lives on this phone. 86% of piano teachers say sight-reading is important but only 7% teach it systematically (Hardy study). Sight Staff is what they would have built.

Why it exists
The problem
Piano students need daily sight-reading drill but Tenuto has only 24 fixed exercises, Notevision has known audio bugs (middle C and octave register as same note), and Piano Marvel costs $290+ — there's no free, comprehensive, offline alternative.
