Need a hand with your practice?

All local features are free, with no registration. Sheet management, numbered notation recognition and editing, and local practice and processing once resources are ready are not unlocked by tipping. Tips are optional support.

Recordings, scores and recognition/editing results are primarily stored on your device. Tuning, analysis, separation and numbered notation recognition do not upload that content for cloud processing. URL downloads, separation model and runtime downloads, and store features such as tips and ratings use the relevant network services.

The sheet library supports multiple photos, PDFs, multi-page reading, songbooks, tags and search. Recognition currently works on a single numbered notation image; multi-page import is not whole-book batch recognition. Check notes, durations, lyrics and chords against the original after recognition.

Your recordings, scores and edits stay on your own device. Tuning, analysis, separation and numbered notation recognition run locally, without sending your music or score images to the cloud for processing.

URL imports download over the internet. Some platforms first download separation models and runtime resources from our website. Tips, ratings and other store features use their respective network services.

Allow microphone access in system settings, close other microphone apps and play one string at a time near the device in a quiet place. Let the note ring naturally. Check the instrument, tuning and reference pitch; results depend on the device, environment and playing.

Import or record a song in My Music, open the player and set a section loop. Adjust speed and pitch as needed. Editing saves a copy; keep a separate backup of important originals.

No. Processing runs on your device without uploading music or score images to us. Some versions first need model downloads and enough free storage. Results can take time and may be inaccurate; use the screen's cancel or retry options.

Check that it is a reachable, valid song, playlist or direct download link, and that network and storage are available. Do not bypass certificate checks for an untrusted source. Do not include passwords, tokens or private-access links in feedback.

Mainly on your device, without account-based cloud sync. Recently Deleted differs from permanent deletion. Uninstalling or clearing data may also remove music, installation credentials and support records. Manage exports and system backups separately.

Tips never renew. They are voluntary one-time purchases, with available methods and prices on the payment screen. You can also use the sharing option. Companions and daily notes are local thank-you content, not real-person chat, coaching or an artist endorsement.

Do not pay again straight away. Keep the order number, reconnect and reopen the app or check unfinished orders as prompted. Completed consumable tips and companions are not guaranteed to return after reinstalling or changing devices. Restore Purchases does not mean restoring all historical support.

Use the App Store or Google Play process for store purchases. Email yizhi401@126.com for Alipay orders, with the order number and issue. We reply to support and privacy requests within 15 working days. Include device, system, app version and reproduction steps, with personal details redacted.
