A calmer practice screen, and a fix for revisiting keys. • The practice screen is quieter — just the note, the beat, and the time. • Revisiting a key you've already mastered now carries you through every chord in it, instead of quietly stopping a few short.

Reference tones you can actually hear. • Low-register reference tones now sit in your phone speaker's strong range, so the note you're being asked to match is clear and loud whether you're playing high on the neck or down in the lower frets. • Audio routing fix — sound now reliably comes through the bottom speaker when the mic is listening, instead of getting demoted to the quiet earpiece.

A calmer way to revisit what you've learned. • Finishing a key centre now opens a quiet celebration, then a mastery screen where you can revisit any key you've mastered. • Three new free-practice modes: practise all your notes, all your chords, or everything together. • Behind-the-scenes stability improvements.

Smoother sessions and a calmer flow. • Body scan now fires only once at the halfway point of a session. • Auto-recovers if the mic stalls after an interruption (Shortcuts, Siri, Control Centre). • Cleaner pool when moving between key centres — no more old notes lingering or balance prompts for chords you can't access. • Bonus rounds require a real 85% to pass. • Mastery screen layout fix — Revisit and Practice pool no longer overlap. • Duration picker now suggests +5 or -5 minutes based on whether you finished your last session.
