It holds a 4.54/5 rating from 13 reviews. > **Bottom Line:** Audio Extractor delivers reliable core utility, but the ad-interrupted conversion flow creates friction for the user base. Transitioning to a non-intrusive monetization model would stabilize the user experience and improve long-term retention. **Best for:** Users needing a simple utility to isolate audio tracks from video files for personal use. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship a non-intrusive ad-removal subscription because conversion-triggered ads are the top complaint → improve user retention ### Outlook: Stable The utility market for file conversion is consolidating around apps that offer cleaner, ad-free experiences. Audio Extractor remains stable but exposed: without a paid tier to replace ad-interrupted workflows, the app will struggle to retain power users as competitors introduce more refined monetization models. - ⚪ The latest release provides only generic bug fixes, signaling a maintenance-mode posture rather than active feature expansion. - 🔴 Advertisements during conversion interrupt the user experience, which risks long-term churn as users seek cleaner, paid alternatives. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.54/5 | | Total Reviews | 13 | | Sentiment | Thrilled (90/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Audio Extractor - MP4 to M4A** (this app) | 4.54/5 | Thrilled | 杏娣 吴 | | [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:** 杏娣 吴 ## Data Sources & Links - **App Store ID:** 6499252952 - **Sources:** 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 Audio Extractor free to use?
