SoundLab is currently exposed: its lack of major updates over the last six months allows rivals to erode its lead in the professional segment. - 🔴 Stability regressions (crashes and data loss) erode the daily active habit, which compounds the rating drag already visible on Android. - 🟢 The 16-track production suite remains a unique differentiator that keeps power users engaged despite current technical friction. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.61/5 | | Total Reviews | 13.4K | | Sentiment | Mixed (55/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **SoundLab - Audio Editor** (this app) | 4.61/5 | Mixed | 孛 刘 | | [MultiTrack DAW](https://marlvel.ai/apps/com-harmonicdog-multitrack) | 4.4/5 | N/A | Harmonicdog | | [Stemz: remover vocal audio pro](https://marlvel.ai/apps/com-mwm-stems) | 4.7/5 | N/A | MWM | | [Voloco: Vocal Recording Studio](https://marlvel.ai/apps/com-resonantcavity-voloco) | 4.8/5 | N/A | Resonant Cavity, Inc | | [BandLab – Music Maker & Beats](https://marlvel.ai/apps/bandlab-music-maker-beats) | 4.7/5 | n/a | BandLab Singapore Pte Ltd | | [Audio Editor - Music editor](https://marlvel.ai/apps/audio-editor-music-editor) | 4.5/5 | N/A | 苏娟 陈 | ## Company Profile - **Developer:** 孛 刘 - **Website:** [https://www.soundlabs.app](https://www.soundlabs.app) - **Social:** [Facebook](https://www.facebook.com/profile.php?id=100094091983002) ## Data Sources & Links - **App Store ID:** 1450417400 - **Google Play ID:** fr.theapp.soundsense - **Dev Site:** [Official Website](https://www.soundlabs.app) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*MultiTrack DAW*](https://marlvel.ai/apps/com-harmonicdog-multitrack) (Harmonicdog) · 4.4/5 Rating - [*Stemz: remover vocal audio pro*](https://marlvel.ai/apps/com-mwm-stems) (MWM) · 4.7/5 Rating - [*Voloco: Vocal Recording Studio*](https://marlvel.ai/apps/com-resonantcavity-voloco) (Resonant Cavity, Inc) · 4.8/5 Rating - [*BandLab – Music Maker & Beats*](https://marlvel.ai/apps/bandlab-music-maker-beats) (BandLab Singapore Pte Ltd) · 4.7/5 Rating - [*Audio Editor - Music editor*](https://marlvel.ai/apps/audio-editor-music-editor) (苏娟 陈) · 4.5/5 Rating - [*Music Editor - Audio Editor*](https://marlvel.ai/apps/music-editor-audio-editor) (BetterApp Tech Co., Limited) · 4.5/5 Rating - [*WavePad Music and Audio Editor*](https://marlvel.ai/apps/wavepad-music-and-audio-editor) (NCH Software) · 4.6/5 Rating - [*Music Mastering: AudioMaster*](https://marlvel.ai/apps/music-mastering-audiomaster) (Future Moments) · 4.5/5 Rating - [*MicSwap MultiTrack: Mic Studio*](https://marlvel.ai/apps/micswap-multitrack-mic-studio) (Future Moments) · 4.6/5 Rating - [*Music Editor: DJ Mixing Studio*](https://marlvel.ai/apps/music-editor-dj-mixing-studio) (Whistle Studios LLC) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is SoundLab free to use?
