How much does it cost?
- $14.99 upfront purchase (current App Store price)
- One-time In-App Purchase for full Handwriting Recognition capabilities
The app is currently transitioning from a paid-only model to a freemium approach. While the store lists a $14.99 price, the developer's strategy is to offer core notation for free while gating the premium handwriting engine behind an IAP.

The outtake for Symphony Pro - Music Notation
Strengths to defend, gaps to attack
Core Strengths
- Industry-leading handwriting recognition engine
- Deep technical capacity (100 staves, 48 instruments)
- Universal Apple ecosystem support (iOS/iPadOS/macOS)
- Strong value perception vs. StaffPad
Critical Frictions
- Critical UI bugs (auto-closing menus)
- Reports of data loss and folder deletion
- Local-only workflow lacks collaboration features
- Unintuitive multi-level menu navigation
Growth Levers
- Integrate OMR (Optical Music Recognition) for score scanning
- Implement cloud-based real-time collaboration
- Full transition to freemium to capture the student market
Market Threats
- Flat's cloud-first collaborative ecosystem
- Dorico's professional engraving engine
- Permanent brand damage from 'app-breaking' stability issues
What are the next best moves?
Fix the 'Project Menu' auto-close glitch immediately.
This is the #1 complaint in recent reviews and is described as making the app 'unusable,' directly causing the declining sentiment trend.
Implement a robust auto-save and iCloud backup redundancy system.
Users report losing entire folders of scores during crashes; for a professional workstation, data loss is a terminal failure point.
Develop a cloud-sync or 'Share to Web' feature.
Nemesis competitor 'Flat' is winning users by offering cross-platform web-sync and collaboration, which Symphony Pro currently lacks.
Feature Gaps vs Competitors
- Cloud-first collaborative editing (available in Flat)
- Integrated social community for score sharing (available in Flat)
- Optical Music Recognition/Scanning (available in Sheet Music Scanner and PlayScore 2)
- Real-time ensemble annotation sync (available in Newzik)
Key Takeaways
Symphony Pro owns a powerful niche with its superior handwriting engine, but it is currently bleeding user trust due to critical stability flaws. If I were the PM, I would halt all feature development to resolve the project menu and data loss bugs, as these 'app-breaking' glitches are the only things preventing this from being the undisputed leader in iPad notation.
