The 4.19-star rating is currently under pressure from high-frequency crash reports that prevent basic file access. ## Monetization Strategy - **Model:** Free - **Tiers:** Free version with no stated subscription or IAP - **Analysis:** The app operates as a free utility with no visible monetization gates or subscription tiers, limiting the developer's ability to fund ongoing maintenance. ## 🔴 User Sentiment (Medium Confidence: 17 of 17 reviews analyzed) {#user-sentiment} - **Overall Rating:** 4.19/5 - **Platform Split:** iOS 4.2/5 (136 ratings) - **Overall Sentiment:** Frustrated - **Note:** The 4.19/5 store rating reflects cumulative history, while the Frustrated sentiment reflects recent user reviews analyzed by our AI pipeline. ### Top Praises - **Organizing sheet music into custom set lists provides a helpful workflow for live performance preparation** - **Importing scanned music from cloud storage services simplifies the process of building a digital library** ### Top Complaints (Impact Areas) - **Frequent application crashes during file access prevent users from opening or viewing their music library** ## SWOT Analysis {#swot} **Core Strengths:** - Multi-format file compatibility reduces user friction **Growth Levers:** - Premium tier could fund missing sync features ## What's New - **Latest (v1.3.8, 10 months ago):** Maintenance update focused on stability improvements and bug fixes. ## App Momentum (Maintenance) {#momentum} - Quiet 10 months, bug fixes only. - Last major release 303 days ago. > **Cadence:** 1 total versions · 0 majors in last 6 months · 302 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} All Sheet Music is a music app that is completely free. With a 4.19/5 rating from 136 reviews, it faces significant user friction. > **Bottom Line:** All Sheet Music requires an immediate stability audit to resolve the crash-on-open behavior that currently prevents basic library access. Addressing these technical failures is the only way to prevent further user churn and stabilize the app's long-term utility. **Best for:** Musicians and students who need a centralized reader for managing and practicing with digital sheet music. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit file-loading logic because frequent crashes during file access are the #1 churn risk → stabilize the user base ### Outlook: Declining The market for digital sheet music is increasingly dominated by apps with active development cycles and robust cloud-sync features. All Sheet Music is currently exposed due to its lack of updates and severe stability issues, which will likely accelerate user migration to more reliable alternatives in the coming quarter. - 🔴 Frequent application crashes during file access prevent users from opening their music library, which directly erodes the app's core value proposition. - 🔴 The 10-month update silence indicates a maintenance-only posture, leaving the app unable to respond to user requests for better Apple Pencil integration. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.19/5 | | Total Reviews | 136 | | Sentiment | Frustrated (25/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **All Sheet Music** (this app) | 4.19/5 | Frustrated | AmoriyA | | [SyncTimer - Ensemble Stopwatch](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) | 5.0/5 | Thrilled | Sebastian Suarez-Solis | | [ヨルシカ](https://marlvel.ai/apps/com-yorushika-sp) | 4.8/5 | N/A | Fanplus, Inc. | | [あいみょん](https://marlvel.ai/apps/net-aimyong-sp) | 4.5/5 | N/A | Fanplus, Inc. | | [イントリズム](https://marlvel.ai/apps/jp-rc-into-rhythm) | 3.5/5 | N/A | RedinC | | [クリープハイプ](https://marlvel.ai/apps/creephyp-sp-browsingapp) | N/A/5 | N/A | Fanplus, Inc. | ## Company Profile - **Developer:** AmoriyA - **Website:** [https://belokan.net/apps/allsheetmusic](https://belokan.net/apps/allsheetmusic) - **Social:** [YouTube](https://www.youtube.com/watch) ## Data Sources & Links - **App Store ID:** 1356048018 - **Dev Site:** [Official Website](https://belokan.net/apps/allsheetmusic) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*SyncTimer - Ensemble Stopwatch*](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) (Sebastian Suarez-Solis) · 5.0/5 Rating | Excellent Sentiment - [*ヨルシカ*](https://marlvel.ai/apps/com-yorushika-sp) (Fanplus, Inc.) · 4.8/5 Rating - [*あいみょん*](https://marlvel.ai/apps/net-aimyong-sp) (Fanplus, Inc.) · 4.5/5 Rating - [*イントリズム*](https://marlvel.ai/apps/jp-rc-into-rhythm) (RedinC) · 3.5/5 Rating - [*クリープハイプ*](https://marlvel.ai/apps/creephyp-sp-browsingapp) (Fanplus, Inc.) · N/A Rating - [*マカロニえんぴつ*](https://marlvel.ai/apps/com-macaroniempitsu-fc) (Fanplus, Inc.) · 3.1/5 Rating - [*¼ learn sight read music tutor*](https://marlvel.ai/apps/learn-sight-read-music-tutor) (Alain Kong) · 4.5/5 Rating - [*100.1 Jack FM*](https://marlvel.ai/apps/100-1-jack-fm) (NRG Media) · 1.0/5 Rating - [*100.1 WJRZ*](https://marlvel.ai/apps/100-1-wjrz) (Beasley Broadcast Group) · 4.8/5 Rating | Excellent Sentiment - [*100.3 The Wolf*](https://marlvel.ai/apps/100-3-the-wolf) (SummitMedia, LLC) · 4.1/5 Rating ## Frequently Asked Questions {#faq} ### Is All Sheet Music free to use?
