This update brings a smarter practice experience, a big Compendium expansion, and a large round of fixes. • Instrument Compendium: four new instruments (bass clarinet, English horn, bass trombone, flugelhorn), interactive fingering diagrams for brass valves and trombone slide positions, instrument deep links and family browsing, and hundreds of verified data corrections — including corrected saxophone fingering charts • Smarter practice: Learn trainers now adapt to your weak spots, prescribe targeted etudes from your actual results, and track improvement honestly in Today's Focus; build a routine directly from your weakest notes • Tuner: a live tendency chip shows how your instrument typically drifts on the note you're playing • Metronome: timing now survives screen lock and background use, plus per-bar swing control • Streak Freeze (Premium): protect your practice streak when life gets in the way • Practice Report: weekly coaching and your report now live in one combined card • Studios: book lessons in multiple lengths from open availability, with clearer scheduling and messaging feedback and more reliable student views • Fixed: practice reminders now fire reliably, audio recovers cleanly after calls and interruptions, "remember me" works on device, cloud-sync merges are more accurate, and dozens of smaller bugs
