MAKE IT YOURS • Work with multiple scale setups at once. • Save favorites and reusable practice plans. • Create custom scales and tunings. • Personalize instrument necks and note colors. • Use left-handed layouts where supported. ON APPLE VISION PRO • Place the Practice Station beside your instrument once, and visionOS puts it back where you left it. • The Station shows the scale, chord, pattern or lesson exercise you picked, on the same fretboard or keyboard the app already draws, at a readable size or at a typical instrument's nominal size. • Reference keeps the shapes in your sightline. Play Along runs a timed example. Follow waits for each note and moves on when it hears or receives it. Harmony shows the next chord before it arrives. • Switch on Listen and the Station lights up the notes you play through the microphone; a MIDI keyboard works too. It never listens until you ask it to. • Keep the tuner in a panel beside the board, and reach Play, Pause, Repeat, Slower, Faster and Stop with Voice Control, without putting the instrument down. • Place the Scale of the Day and Practice Streak widgets in your surroundings. • Explore, Learn, Tools, your practice history and everything you have already bought are the same app, in its own window beside the Station. Instrument Scales is available on iPhone, iPad, Mac, and Apple Vision Pro, with a localized interface in English, Brazilian Portuguese, Japanese, Spanish, German, and Simplified Chinese. Start with the free essentials. Optional Pro and Max purchases unlock additional tools, lessons, and practice features.
