I've always dreamed of playing the piano. As an adult, I finally started taking classical piano lessons after work. The hardest part for a beginner? Instantly recognizing notes on a staff. My teacher would hand-draw random notes in a manuscript book for me to practice between lessons. That's when it hit me — why not turn this into an app? It saves the teacher time and the student money. That's how SightReading was born. Features: • Endless random note practice • On-screen piano keyboard with realistic sound • Treble clef, bass clef, and grand staff • Timed challenge — race the clock for the highest score • Level mode — progress from beginner to master • 11 color themes to personalize your experience • Customizable note range and sharps/flats practice • Statistics to track your improvement

Verdict

The call

The clearest difference is in-app purchases: Sight reading at none against 懂音律's 3. Sight reading also leads on ratings volume (1.3K vs 242). 懂音律's advantage is update cadence (every 10 days vs every 128 months) and iOS requirement (14.0 vs 16.0). On price, rating, review sentiment and device support there is nothing between them.
