(Strategic Takeaway) {#so-what} Audio Class Notes Free - Record, Share, and Tag School Lectures is an education app that is completely free. With a 4.2/5 rating from 64 reviews, it shows mixed user reception. > **Bottom Line:** Audio Class Notes is a legacy utility that no longer meets modern reliability standards, as evidenced by persistent data-loss reports. Sunset the product to prevent further brand erosion, as the technical debt exceeds the value of the remaining user base. **Best for:** High school and college students requiring audio-based lecture review tools. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the product because the codebase lacks modern permission handling and cloud-sync support → eliminate brand drag ### Outlook: Declining The market for student note-taking tools has shifted toward cloud-native, AI-transcription platforms that offer cross-device synchronization. Audio Class Notes lacks the infrastructure to compete in this environment, and its continued presence in the store risks damaging the developer's reputation due to unresolved data-loss bugs. - 🔴 The 11-year update gap confirms a total lack of maintenance, which directly causes the microphone permission errors reported by users on newer hardware. - 🔴 Persistent file-saving failures and corrupted Dropbox uploads indicate the backend infrastructure is no longer functional, leading to inevitable user churn. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.2/5 | | Total Reviews | 64 | | Sentiment | Mixed (45/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Audio Class Notes Free - Record, Share, and Tag School Lectures** (this app) | 4.2/5 | Mixed | BlackMuse Software | | [AlgoApp - Flashcards](https://marlvel.ai/apps/algoapp-flashcards) | 4.5/5 | n/a | AlgoApp Inc | | [Elevate - Brain Training Games](https://marlvel.ai/apps/elevate-brain-training-games) | 4.7/5 | n/a | The Mind Company | | [Flashcards Deluxe](https://marlvel.ai/apps/flashcards-deluxe) | 4.5/5 | N/A | OrangeOrApple.com | | [Flash Cards Flashcards Maker](https://marlvel.ai/apps/flash-cards-flashcards-maker) | 4.0/5 | Mixed | Infinite Wave Media, LLC | | [Flashcards maker - AI generate](https://marlvel.ai/apps/flashcards-maker-ai-generate) | 4.1/5 | Mixed | Teleprompter LLC | ## Company Profile - **Developer:** BlackMuse Software - **Website:** [https://www.blackmusesoftware.com/audio-class-notes.html](https://www.blackmusesoftware.com/audio-class-notes.html) ## Data Sources & Links - **App Store ID:** 388847376 - **Dev Site:** [Official Website](https://www.blackmusesoftware.com/audio-class-notes.html) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Elevate - Brain Training Games*](https://marlvel.ai/apps/elevate-brain-training-games) (The Mind Company) · 4.7/5 Rating - [*Flashcards Deluxe*](https://marlvel.ai/apps/flashcards-deluxe) (OrangeOrApple.com) · 4.5/5 Rating - [*Flash Cards Flashcards Maker*](https://marlvel.ai/apps/flash-cards-flashcards-maker) (Infinite Wave Media, LLC) · 4.0/5 Rating - [*Flashcards maker - AI generate*](https://marlvel.ai/apps/flashcards-maker-ai-generate) (Teleprompter LLC) · 4.1/5 Rating - [*Impulse - Brain Training*](https://marlvel.ai/apps/impulse-brain-training) (GMRD Apps Limited) · 4.6/5 Rating - [*Peak - Brain Training*](https://marlvel.ai/apps/peak-brain-training) (Synaptic Labs) · 4.7/5 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 ## Frequently Asked Questions {#faq} ### Is Audio Class Notes still supported?
