The app's current stability-focused approach is sufficient for its niche, but it must address core audio performance to prevent churn to more modern, actively maintained alternatives. - ⚪ The 42-day update cadence indicates a stable maintenance posture rather than active feature expansion, limiting growth potential. - 🟢 Core amplification functionality remains a high-utility, low-friction tool that serves a specific, recurring need for public speakers. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Speaker Mic - Voice Amplifier** (this app) | N/A/5 | N/A | 杨柳 孙 | | [JustPlay: Earn Money or Donate](https://marlvel.ai/apps/justplay-earn-money-or-donate) | 4.4/5 | n/a | JustPlay GmbH | | [YouTube TV](https://marlvel.ai/apps/com-google-ios-youtubeunplugged) | 3.7/5 | n/a | Google | | [BestPlay: Play Games & Earn](https://marlvel.ai/apps/bestplay-play-to-earn-donate) | 4.6/5 | n/a | Bestplay | | [BIBLIOTECA LDM](https://marlvel.ai/apps/biblioteca-ldm) | 4.8/5 | Mixed | Esteban Gonzalez | | [CIPHER Zombies](https://marlvel.ai/apps/cipher-zombies) | N/A/5 | N/A | Jeffrey Bemelmans | ## Company Profile - **Developer:** 杨柳 孙 ## Data Sources & Links - **App Store ID:** 6760217493 - **Sources:** App store metadata. ## Related Intel Reports - [*JustPlay: Earn Money or Donate*](https://marlvel.ai/apps/justplay-earn-money-or-donate) (JustPlay GmbH) · 4.4/5 Rating - [*YouTube TV*](https://marlvel.ai/apps/com-google-ios-youtubeunplugged) (Google) · 3.7/5 Rating - [*BestPlay: Play Games & Earn*](https://marlvel.ai/apps/bestplay-play-to-earn-donate) (Bestplay) · 4.6/5 Rating - [*BIBLIOTECA LDM*](https://marlvel.ai/apps/biblioteca-ldm) (Esteban Gonzalez) · 4.8/5 Rating - [*CIPHER Zombies*](https://marlvel.ai/apps/cipher-zombies) (Jeffrey Bemelmans) · N/A Rating - [*DramaBox - Stream Drama Shorts*](https://marlvel.ai/apps/dramabox-stream-drama-shorts-1) (STORYMATRIX) · 4.7/5 Rating - [*DramaWave - Dramas & Reels*](https://marlvel.ai/apps/dramawave-dramas-reels) (SKYWORK AI PTE LTD) · 4.7/5 Rating - [*PACIFIC RIM: JAEGER VS KAIJU BATTLE*](https://marlvel.ai/apps/pacific-rim-jaeger-vs-kaiju-battle) (Warner Bros.) · 3.5/5 Rating - [*PLAYZONE - Play & Earn Rewards*](https://marlvel.ai/apps/money-well-earn-rewards) (Vanessa Calatayud Gomis) · 2.5/5 Rating - [*TikTok Pro - Events*](https://marlvel.ai/apps/com-ss-iphone-ugc-tiktok-pro) (TikTok Ltd.) · 4.6/5 Rating ## Frequently Asked Questions {#faq} ### Is Speaker Mic suitable for professional presentations?
