The lack of development activity suggests the developer views the software as a static support layer, meaning the app will likely remain stable until OS-level changes force a mandatory update or sunset. - ⚪ The 1,599-day update gap confirms the app is in maintenance mode, meaning no new features will likely emerge to drive growth. - 🔴 The lack of recent updates creates a growing risk of OS-level incompatibility, which would directly impact the utility of the associated hardware. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 1/5 | | Total Reviews | 3 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **ZDEER SOUND** (this app) | 1/5 | N/A | Wuhan Zuo Dian Technology Co., Ltd | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [App For Siri Commands Tips](https://marlvel.ai/apps/app-for-siri-commands-tips) | N/A/5 | N/A | Anh La Phan Son | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Bin Days - Bin Reminder](https://marlvel.ai/apps/bin-days-bin-reminder) | N/A/5 | N/A | Vicki Partridge | ## Company Profile - **Developer:** Wuhan Zuo Dian Technology Co., Ltd - **Website:** [https://www.zdeer.com](https://www.zdeer.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/zdeer-sound/id1623283973?uo=4) - **Dev Site:** [Official Website](https://www.zdeer.com) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*App For Siri Commands Tips*](https://marlvel.ai/apps/app-for-siri-commands-tips) (Anh La Phan Son) · N/A Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Bin Days - Bin Reminder*](https://marlvel.ai/apps/bin-days-bin-reminder) (Vicki Partridge) · N/A Rating - [*Controller Tester FGC*](https://marlvel.ai/apps/controller-tester-fgc) (Aaron Lowe) · 5.0/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Gear Ratio Calculator & RPM*](https://marlvel.ai/apps/cog-gear-ratio-calculator) (Linh Phan Nhat Khanh) · N/A Rating - [*NordVPN: VPN Fast & Secure*](https://marlvel.ai/apps/com-nordvpn-nordvpn) (Nordvpn S.A.) · 4.7/5 Rating - [*Pick and Pull: Junkyard Finder*](https://marlvel.ai/apps/pick-and-pull-junkyard-finder) (Vladimir Kostadinov Stoyanov) · 3.7/5 Rating ## Frequently Asked Questions {#faq} ### Is ZDEER SOUND required to use ZDEER hardware?
