Clarinet Fingering Chart Tool is currently exposed due to its reliance on maintenance-only updates, which fail to address the technical regressions now driving negative sentiment. - 🔴 Frequent crashes post-update prevent access to learning content, which directly causes user churn and negative sentiment. - ⚪ The current maintenance-only release cadence suggests a lack of active feature expansion, limiting the ability to compete on new functionality. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.77/5 | | Total Reviews | 379 | | Sentiment | Excited (65/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 4 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Clarinet Fingering Chart Tool** (this app) | 3.77/5 | Excited | Andriy Holovchak | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Money Matrix (CAD)](https://marlvel.ai/apps/money-matrix-cad) | 5.0/5 | N/A | Blooming Kids Software LLC | | [Quran Treasure Island for Kids](https://marlvel.ai/apps/quran-treasure-island-for-kids) | 4.9/5 | Mixed | Akeela Manekia | | [Valencia College - MyVC](https://marlvel.ai/apps/valencia-college-myvc) | 5.0/5 | N/A | Valencia College | | [Verbi: Learn a New Language](https://marlvel.ai/apps/verbi-learn-a-new-language) | 4.3/5 | n/a | ACADIA LABS INC. | ## Company Profile - **Developer:** Andriy Holovchak - **Website:** [https://www.trumpetfingering.com/](https://www.trumpetfingering.com/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/clarinet-fingering-chart-tool/id6478438560?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.clarinetfingeringchart&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.trumpetfingering.com/) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Valencia College - MyVC*](https://marlvel.ai/apps/valencia-college-myvc) (Valencia College) · 5.0/5 Rating - [*Verbi: Learn a New Language*](https://marlvel.ai/apps/verbi-learn-a-new-language) (ACADIA LABS INC.) · 4.3/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating - [*천자문 워치*](https://marlvel.ai/apps/app--385) (kim juyoung) · N/A Rating - [*천자문 공부 도우미*](https://marlvel.ai/apps/app--382) (kim juyoung) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Clarinet Fingering Chart Tool suitable for beginners?
