It holds a 3.44/5 rating from 9 reviews. > **Bottom Line:** The one-time purchase model is a strong retention lever, but the lack of stem export and persistent audio artifacts currently cap the app's professional utility. Addressing these technical gaps would unlock the app's potential as a primary production tool for its loyal user base. **Best for:** Music producers, remixers, and musicians requiring stem isolation for professional production workflows. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship native stem export functionality because it is the top-requested workflow gap → increase professional adoption ### Feature Gaps vs Competitors - Native stem export functionality (missing here, standard in professional production tools) ### Outlook: Mixed The music utility market is consolidating around tools that offer frequent AI model updates and deep DAW integration. Let’s Unmix Audio Unit remains exposed due to its stalled development, and without a move to address core export limitations, it will likely lose its position to more active competitors. - 🔴 The 18-month development silence suggests the app is in maintenance mode, which will likely lead to user churn as production workflows evolve. - 🟢 The one-time purchase model continues to attract users who are fatigued by subscription-based audio tools, providing a stable, if limited, user base. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.44/5 | | Total Reviews | 9 | | Sentiment | Mixed (50/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Let’s Unmix Audio Unit** (this app) | 3.44/5 | Mixed | Hikaru Tsuyumine | | [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:** Hikaru Tsuyumine - **Website:** [https://vocalextractor.com/en](https://vocalextractor.com/en) - **Social:** [YouTube](https://www.youtube.com/watch) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/lets-unmix-audio-unit/id1631417268?uo=4) - **Dev Site:** [Official Website](https://vocalextractor.com/en) - **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 - [*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 - [*100.7 KIK-FM*](https://marlvel.ai/apps/100-7-kik-fm) (Hubbard Radio) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Let’s Unmix Audio Unit suitable for professional music production?
