For a bug report, include your device, OS, app version, steps, expected behavior, and actual behavior. Sending a recording is optional. Do not send personal information or scores and audio you cannot share.

Free features

Use the tuner and metronome, import, save, and view unlimited .shami / JSON scores, practice individual notes with automatic progression when the correct pitch is detected, practice whole pieces, and record, play back, and share. The bundled Sakura Sakura includes a free trial of Plus practice and analysis features.

ShamiTrainer Plus

A one-time purchase unlocks phrase repetition, pitch, timing, and duration measurements, and post-recording analysis of automatic recordings linked to a score. The price is $5.99 (US price; one-time purchase; prices vary by region). This is a separate purchase from ShamiScore Pro.

If you already purchased Plus, use the same Apple Account and choose Restore Purchases on the Plus screen. For refunds, use Apple's refund service.

Recordings that cannot be analyzed

Analysis requires score information saved at recording time. Manual and legacy recordings without it remain playable and shareable but cannot be compared with a score. Real performances may contain undetected or incorrectly detected notes. Measurements do not represent overall performance quality.

Microphone and AI

Check microphone permission in OS settings. Analysis runs on your device. When Apple Intelligence is unavailable, predefined practice suggestions based on measurements remain available.
