USD 9.99 one-time purchase. No subscription. How it works
Import, choose, practice.
A score becomes a playable practice flow: pick the part you need, adjust the playback, and keep every piece organized.
Choose a part
Open song detail and choose the violin, viola, or cello part you want to practice when a score contains multiple playable parts.
Practice in the player
Follow falling notes over string lanes with finger labels, positions, timing controls, count-in, and optional fingerboard guidance.
Organize your library
Use collections, search, metadata, and Source Files scanning to keep practice material easy to find without hiding your files.
Built for real practice
Use StringFlow with music you actually play.
StringFlow is designed around recognizable practice situations, from solo repertoire to ensemble parts and accompaniment work.
Solo repertoire
Import a Bach cello suite, a violin étude, or a viola exercise, then slow down difficult passages while fingerings stay visible.
Ensemble parts
Practice second violin, viola, or cello in a quartet while hearing the other parts around you.
Accompaniment practice
Bring your part forward while learning, then mute it and play with the accompaniment when you are ready.
Practice player
The player is the practice surface.
The falling-note player turns supported string parts into timing, string lanes, note labels, finger labels, positions, and musical context.
✓ Falling notes over instrument string lanes
✓ Current and upcoming note HUD
✓ Finger labels, positions, ties, and slur arcs
✓ Speed, spacing, seek, skip, and count-in controls
✓ Exact value entry for careful practice setup
Appearance
Native in light and dark.
Preview the same player and library moments in either appearance. StringFlow follows the look of your device.
Library and Source Files
Your scores stay visible.
Source Files are the original score files you bring to StringFlow. The app can use a default local folder or scan a folder you already manage, such as iCloud Drive, Dropbox, or another synced local folder.
✓ Collections are metadata, not physical folders
✓ Search by title, filename, format, instrument, part, note count, and parsed metadata
✓ Scan a Source Files folder you already use
✓ Adopt files already in Source Files instead of creating duplicate clutter
✓ Rename imported scores to keep your library tidy
✓ Keep converted caches separate from shared source folders
Library tools
Organize without losing ownership.
Collections, settings, and Source Files workflows keep practice material organized while leaving the original score files understandable.
Supported instruments
For violin, viola, and cello.
StringFlow focuses on bowed-string practice first, with dedicated visual practice workflows for violin, viola, and cello. It is designed to help players who are searching for a violin practice app, viola practice app, or cello practice app built around their own MusicXML and MIDI files. Double bass support is being explored for a future version.
Violin
A visual violin practice app for following violin parts with string lanes, finger labels, and position-aware fingering guidance.
Viola
A focused viola practice app that brings viola parts into the same visual practice flow, including custom fingering presets.
Cello
A practical cello practice app with instrument-aware string lanes and fingering suggestions for cello parts.
