Piano Code turns sheet music into an interactive practice studio. Browse a growing library of tunes, hear them played back, and learn them note by note on a built-in 88-key keyboard. KEY FEATURES • MIDI Playback — Tap any tune to hear it played from its score. The staff itself acts as the progress indicator, so you always know exactly where you are in the piece. • Virtual Keyboard Follow-Along Training — A full 88-key piano is built right in. Notes light up on both the staff and the keyboard to guide your hands: upcoming notes in purple, correct hits in green, mistakes flash red. Play along with mouse, touch, or keyboard input. • Track Your Progress — Time your practice sessions and log every tune you work on. Your training records sync to your account so you can pick up right where you left off. Whether you're starting from scratch or polishing a favorite piece, Piano Code helps you read, hear, and play — one note at a time.

Verdict
The clearest difference is in-app purchases: Piano Code at none against PiaTune's 1. PiaTune's advantage is update cadence (every 2 weeks vs every 12 months). On price, ads, device support and iOS requirement there is nothing between them.
