NNS Pro: The Professional Nashville Number System App

Stop just reading charts—own your performance. NNS Pro is the definitive Nashville Number System tool designed for bands, worship teams, and session musicians. Built by musicians for musicians, our platform solves the real-world friction of rehearsals and live performances by digitizing your charting workflow with professional-grade precision.

Why Professional Musicians Choose NNS Pro
• Built for the Nashville Number System: Unlike generic apps that force you to adapt, NNS Pro supports industry-standard notation natively—including rhythmic pushes, complex dynamics, repeat structures, and numbered endings.
• Instant, No-Rewrite Transposition: Perform in any key with confidence. Tap a key badge to re-map every chord in real time—perfect for mid-song key changes or last-minute rehearsal adjustments.
• Anchored, Professional-Grade Annotation: Tired of notes shifting when you transpose? Our annotations are intelligently anchored to their measures. Draw, highlight, and add text that stays exactly where you need it, regardless of key, font scale, or screen size.
• Stage-Ready Performance Mode: Your device becomes a live-ready instrument. Swipe through setlists, manage tempo with a live-beat metronome, and keep your band locked in with a clear, high-contrast interface.

Your Entire Library, Ready in Minutes
Switching to a better charting tool shouldn't mean leaving your work behind. NNS Pro is designed for an immediate, zero-friction transition:
• Native Migration: Instantly import and convert your existing library from other platforms (including .1ch, .1nb, and .nns formats). Our system validates your structure and converts it into native, fully-editable NNS Pro charts automatically.
• Instant Quick-Start: Don’t have time to re-chart before your next gig? Simply snap a photo of your paper charts or import existing PDFs. You can use these image-based documents immediately within your setlists and folders while you migrate your high-priority songs to our native format on your own timeline.

Total Workflow Autonomy
Most apps lock you into their structure; NNS Pro gives you total control.
• Library Management: Organize your music, favorites, and setlists with a robust, nested folder system that mirrors your personal repertoire—not the app’s default structure.
• Drag-and-Drop Control: Reorder measures, songs, and setlist items with intuitive drag-and-drop. Use powerful batch operations to handle large libraries in seconds.
• Bespoke Visuals: Customize your reading experience. Adjust title sizes, dynamic font scaling, and spacing to suit your sight-reading style. Toggle between professional notation preferences (m/-, °/dim) to match your personal standard.

Advanced Rehearsal & Sync Tools
• Practice Smarter: Link YouTube videos or local audio files directly to your charts.
• Cloud Sync & Collaboration: Keep your library in sync across all iOS and Android devices. Share setlists effortlessly with bandmates so everyone is always on the same page.
• Professional Flexibility: Import existing charts, export to PDF/PNG, and maintain a seamless workflow from studio to stage.
