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

On price, review sentiment and device support there is nothing between them.
