The only material shifts are in the analytical assessment of the app's long-term viability, which now emphasizes the risk of OS-level failure. **Overall trend**: Stable **Compared at**: 2026-08-28 ### Medium-impact changes - **[Added] OS Incompatibility Risk** (swot) - **[Shifted] Outlook Narrative** (positioning) ## App Momentum (Zombie) {#momentum} - No updates for 43 months. - Maintenance-mode status confirmed. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1315 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Smart Headphone is an utilities app that is completely free. It holds a 5/5 rating from 1 review. > **Bottom Line:** Smart Headphone offers a specialized calibration mechanism, but the multi-year development silence suggests the project is effectively abandoned. Users should look toward hardware-native solutions, as the lack of maintenance makes long-term reliability unlikely. **Best for:** Headphone users seeking to calibrate audio output to their specific hearing capabilities. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the application because the 43-month development gap makes maintenance unviable → reduce brand risk ### Outlook: Declining The audio utility market is consolidating around hardware-integrated software, leaving standalone apps like Smart Headphone without a clear path to growth. The lack of development activity over the last three years suggests the app will continue to lose relevance as modern OS updates break legacy features. - 🔴 The 1,316-day update gap indicates the app is in maintenance mode, which will eventually lead to failure on newer OS versions. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Smart Headphone** (this app) | 5/5 | N/A | 平 赵 | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** 平 赵 - **Website:** [https://www.spatial-sound-studio.com/](https://www.spatial-sound-studio.com/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/smart-headphone/id1666594168?uo=4) - **Dev Site:** [Official Website](https://www.spatial-sound-studio.com/) - **Sources:** App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Smart Headphone still being updated? No, the app has not received an update since January 2023, which is over 43 months of inactivity. ### Does Smart Headphone work with all headphones?
