Built for the working musician
Every feature in NNS Pro was designed around one question: what does a musician actually need in rehearsal and on stage?
Charting
Full NNS Notation Support
Create charts with the full Nashville Number System vocabulary: chord qualities (major, minor, diminished, augmented), seventh chords, slash chords, suspended chords, and altered extensions.
Articulation & Dynamics
Add accents, marcato marks, staccato dots, fermatas, crescendos, decrescendos, and dynamic levels (p, mp, mf, f, ff) directly to any chord or measure.
Rhythm Notation
Mark chord durations with whole, half, quarter, eighth, and sixteenth note symbols. Add push/anticipation marks, diamond holds, and cutoff marks.
Repeat & Navigation Symbols
Full support for measure repeats (%), section repeats (||: :||), first/second endings, D.S. al Coda, D.C. al Fine, Segno, and Coda markers.
Chart Customization
Full Display Control
Customize section sizing, chord spacing, font colors, and fixed measures per line. Make every chart look exactly the way you want it — no compromises.
Dynamic Font Scaling
Zoom in or out and the layout adjusts in real time so your charts are always readable in portrait or landscape mode.
Custom Annotation Layers
Draw, highlight, and add text notes directly on any chart. Annotations are stored on a dedicated layer and automatically scale when you resize the chart — no manual repositioning needed.
Organization
Song Library
Organize all your charts in a searchable library. Organize songs by genre, artist, group or any other suitable criteria for fast retrieval.
Favorites
Favorite frequently used songs to pin them for fast access across all devices. Organize favorites in folders to find the right chart in seconds.
Cloud Sync
All charts and setlists are automatically synced to the cloud so they’re always up to date on every device you own.
Transposition
Instant Key Changes
Select any of the 12 major and minor keys and watch every chord on every chart instantly re-map. No rewriting required.
Mid-Song Modulations
Insert modulation markers anywhere in a chart. NNS Pro tracks each section’s key center and transposes accordingly.
Enharmonic Intelligence
NNS Pro automatically chooses the most readable enharmonic spelling for each key — no awkward double sharps or double flats.
Performance
Play Mode
Full-screen, touch-friendly chart view designed for live performance. Focus on your music, not your device.
Practice Mode with Media
Link YouTube videos and local audio files to any chart. Practice along with the actual recording while following your chart.
Setlist Management
Build setlists from your song library, drag-and-drop to reorder songs, and simply swipe to navigate between songs without leaving the stage view.
Import & Migration
Import from other music charting apps
Already have a chart library in another app? Import directly from other popular formats. Get up and running without recreating your entire catalog from scratch.
Bundle Export & Sharing
Export individual songs or entire bundles to share songs, favorites, or setlists with bandmates or back up your library. Import bundles received from others to quickly expand your collection.
Shared Band Account Sync
Need everyone on the same version fast? Use a shared band account and every chart, setlist, and update is synced so the whole team always has the latest changes.
